Abstract

Disclosed is an image forming method for an electrophotographic photoreceptor, comprising steps of: PA1 (1) charging said photoreceptor which is moved in a predetermined direction, PA1 (2) imagewise exposing on said charged photoreceptor, PA1 (3) developing said imagewise exposed photoreceptor with a developer to form a toner image, PA1 (4) transferring said toner image onto an image receiving material, and PA1 (5) cleaning a residual toner on said photoreceptor with a cleaning blade after transferring said toner image, wherein said cleaning blade has a fixed end portion and a free end portion, said cleaning step comprising: PA1 urging said free end portion in a direction counter to said predetermined direction of the photoreceptor, wherein said photoreceptor has a static friction coefficient of not more than 1.0 to said cleaning blade so that said free end portion of said cleaning blade is oscillated in an amplitude of 10 .mu.m to 200 .mu.m with the movement of the photoreceptor.
