ABSTRACT:
An image forming apparatus includes a memory distributing unit arranged between a transfer unit and a developing unit which develops an electrostatic latent image formed on a photoconductive drum and cleans the drum surface. The distributing unit has a brush formed of bundles of electrically conductive fibers contacting the circumferential surface of the drum. A predetermined voltage is applied from a power source to the fiber bundles so that residual developing agents on the drum surface are attracted to the fiber bundles. The distributing unit includes a lining member which is formed of an insulating material and presses the brush against the drum surface to prevent the attracted developing agent from scattering from the fiber bundles.
