Abstract
An image forming apparatus including: a rotatable image-carrier; a charging unit that contacts and charges a surface of the image-carrier; an exposing unit that exposes the surface and forms a latent-image; a developing unit that develops the latent-image with a developer; a transfer unit that transfers a developed-toner-image onto a transfer-receiving member; a cleaning unit that is provided with a plate shaped cleaning member having a free end that faces upwards a corner portion of the free end contacting the surface, the cleaning member cleaning off developer remaining on the surface after transfer, and a developer pooling member provided between the cleaning member and the transfer unit, that temporarily pools the cleaned off developer at the free end; and a friction-coefficient reducing unit that reduces a friction-coefficient at the surface, and that reduces the friction-coefficient during non-image forming period to less than that during image forming period is provided.
