Patent ID: 7978998

Claim:
An image forming apparatus comprising: a first image bearing member which bears a toner image; a second image bearing member which bears a toner image; an endless intermediate transfer member which is rotatable; a first transfer member which transfers a toner image charged in a normal polarity from the first image bearing member onto the endless intermediate transfer member; a second transfer member which transfers a toner image charged in the normal polarity from the second image bearing member onto the endless intermediate transfer member; a first cleaning member that collects toner from the first image bearing member; a second cleaning member that collects toner from the second image bearing member; and a charge member which charges residual toner remaining on the endless intermediate transfer member after the transfer of a toner image from the endless intermediate transfer member onto a recording material to a polarity opposite to the normal polarity, wherein the image forming apparatus is capable of performing in (1) a first mode in which a toner image on the second image bearing member is transferred onto the endless intermediate transfer member so that the toner image on the second image bearing member is overlapped on the toner image transferred onto the endless intermediate transfer member from the first image bearing member, and (2) a second mode in which only a toner image on the second image bearing member is transferred on a recording material via the endless intermediate transfer member, and wherein in a case where a toner image is continuously transferred on a plurality of recording materials in the first mode, the first transfer member moves the residual toner charged by the charge member from the endless intermediate transfer member to the first image bearing member, so that the first cleaning member collects the residual toner moved to the first image bearing member, and in a case where a toner image is continuously transferred on a plurality of recording materials in the second mode, the second transfer member moves the residual toner charged by the charge member from the endless intermediate transfer member to the second image bearing member, so that the second cleaning member collects the residual toner moved to the second image bearing member.
