Abstract:
An image forming apparatus includes: a drum unit including a photosensitive drum; a belt unit; and a secondary transfer member. The belt unit includes: a first roller; a second roller spaced apart from the first roller; an intermediate transfer belt supported by the first roller and the second roller; and a primary transfer member. The intermediate transfer belt includes: a first portion; and a second portion. The first portion has an upstream end and a downstream end in a first direction. The second portion has an upstream end and a downstream end in a second direction. The primary transfer member is configured to transfer a toner image from the photosensitive drum to the first portion. The secondary transfer member is capable of contacting the downstream end of the second portion, and is configured to transfer the toner image from the intermediate transfer belt to a sheet.

Claim (Index 14):
An image forming apparatus comprising:\n a main casing; a drum unit attachable to and detachable from the main casing, the drum unit comprising a photosensitive drum; a belt unit attachable to and detachable from the main casing, the belt unit comprising:\n a first roller; \n a second roller spaced apart from the first roller; \n an intermediate transfer belt supported by the first roller and the second roller, the intermediate transfer belt comprising:\n a first portion positioned between the first roller and the second roller, the first portion being configured to be moved in a first direction directed from the first roller to the second roller when the intermediate transfer belt is circularly moved over the first roller and the second roller, the first portion having an upstream end and a downstream end in the first direction, the upstream end of the first portion being in contact with the first roller, the downstream end of the first portion being in contact with the second roller; \n a second portion positioned between the first roller and the second roller, the second portion being configured to be moved in a second direction directed from the second roller to the first roller when the intermediate transfer belt is circularly moved over the first roller and the second roller, the second portion having an upstream end and a downstream end in the second direction, the upstream end of the second portion being in contact with the second roller, the downstream end of the second portion being in contact with the first roller; \n a third portion positioned between the first portion and the second portion, the first roller having an outer circumferential surface exclusively in contact with the third portion, the third portion being configured to be moved along the outer circumferential surface of the first roller from the downstream end of the second portion toward the upstream end of the first portion when the intermediate transfer belt is circularly moved over the first roller and the second roller; and \n a fourth portion positioned between the first portion and the second portion, the second roller having an outer circumferential surface exclusively in contact with the fourth portion, the fourth portion being configured to be moved along the outer circumferential surface of the second roller from the downstream end of the first portion toward the upstream end of the second portion when the intermediate transfer belt is circularly moved over the first roller and the second roller; \n \n a primary transfer member positioned between the first roller and the second roller, the primary transfer member being configured to transfer a toner image from the photosensitive drum to the first portion; and \n a first sheet guide positioned opposite to the first portion with respect to the second portion, the first sheet guide being configured to guide a conveyance of a sheet in a sheet conveying direction toward a prescribed position on the second portion of the intermediate transfer belt, the prescribed position being positioned upstream of the downstream end of the second portion in the second direction, the prescribed position being positioned closer to the downstream end of the second portion in the second direction than to the upstream end of the second portion in the second direction; and \n a secondary transfer unit attachable to and detachable from the main casing, the secondary transfer unit comprising:\n a second sheet guide configured to guide the conveyance of the sheet in the sheet conveying direction toward the prescribed position on the second portion of the intermediate transfer belt in cooperation with the first sheet guide; and \n a secondary transfer member capable of contacting the intermediate transfer belt at a position closer to the downstream end of the second portion than to the upstream end of the first portion so that the intermediate transfer belt is nipped between the secondary transfer member and the first roller, the secondary transfer member being configured to transfer the toner image from the intermediate transfer belt to the sheet guided toward the prescribed position by the first sheet guide and the second sheet guide.
