Title:
電子写真画像形成方法
Document Type and Number:
Japanese Patent JP7077730
Kind Code:
B2
Abstract:
To provide an electrophotographic image formation method that can maintain high cleaning properties over a long period upon using a hardening type OCL photoreceptor.SOLUTION: An electrophotographic image formation method of the present invention has, using an organic photoreceptor (1), at least a charge step, an exposure step, a developing step, a transfer step, a fixation step and a cleaning step. The organic photoreceptor (1) has: a conductivity supporting body (1a); a photosensitive layer (1c) that is arranged on the conductivity supporting body (1a); and a protection layer (1d) that is arranged on the photosensitive layer (1c). The protection layer (1d) contains a polymerization hardened material polymerizing a conductivity particle having polymerizable monomer and a polymerizable group. In the cleaning step, a toner retrieval rate by a toner scratch member (61) arranged on an upstream side further than a cleaning blade (62) is equal to or less than 5%.SELECTED DRAWING: Figure 2
