ABSTRACT:
In an image forming apparatus, a toner image, formed by developing an electrostatic latent image on the photoreceptor, is primarily transferred to an intermediate transfer member and is secondarily transferred to a recording sheet. The image forming apparatus is provided with a retractable transfer member, which secondarily transfers the toner image on the recording sheet, and a retractable cleaning member, which removes a residual toner on the intermediate transfer member after the secondary transfer. In the above apparatus, when the primary transfer and the secondary transfer are not being performed, the transfer member and the cleaning member are allowed to contact with or retract from the intermediate transfer member.
