Claim:
1. An image forming apparatus comprising: a main casing; a sheet supply tray configured to feed a sheet and movable in a moving direction from an outer position in which the sheet supply tray is outside the main casing to an inner position in which the sheet supply tray is inside the main casing; a photosensitive drum; an LED unit configured to expose the photosensitive drum to light and disposed between the photosensitive drum and the sheet supply tray in a vertical direction; a belt unit including a first roller, a second roller, and an intermediate transfer belt stretched around the first roller and the second roller, the intermediate transfer belt being disposed confronting the photosensitive drum from above and contacting the photosensitive drum; a primary transfer roller disposed such that the intermediate transfer belt is interposed between the primary transfer roller and the photosensitive drum; a secondary transfer roller disposed such that the intermediate transfer belt is interposed between the first roller and the secondary transfer roller; a first conveying roller disposed between the LED unit and the sheet supply tray in the vertical direction; a second conveying roller configured to convey a sheet from the first conveying roller to the secondary transfer roller, the second conveying roller being disposed between the LED unit and the sheet supply tray in the vertical direction and downstream from the first conveying roller in a direction the same as the moving direction; and a tray disposed between the LED unit and the sheet supply tray in the vertical direction, the tray being movable in a direction the same as the moving direction from an outer position in which the tray is outside the main casing to an inner position in which the tray is inside the main casing, the tray including a first follower roller and a second follower roller, the first follower roller being located below the first conveying roller when the tray is at the inner position, the second follower roller being located below the second conveying roller when the tray is at the inner position, the first conveying roller and the second conveying roller being configured to receive a driving force so as to convey a sheet with the first follower roller and the second follower roller toward the second transfer roller, and the first conveying roller and the second conveying roller being positioned inside the main casing when the tray is located at the outer position.
