Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD FOR MANUFACTURING THE SAME, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2021124670
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that prevents the generation of black spots even after a long-term use in an electrification roller process and is excellent in durability, a method for manufacturing the same, and an electrophotographic image forming apparatus.MEANS FOR SOLVING THE PROBLEM: An electrophotographic photoreceptor of the present invention is an electrophotographic photoreceptor having at least an intermediate layer, a charge generating layer, a charge transport layer, and a protective layer sequentially laminated on a conductive support. The intermediate layer contains, in its surface, at least rutile type titanium oxide particles surface-modified with an inorganic compound. The thickness of the charge transport layer is within a range of 25 to 40 μm. The protective layer contains at least a charge transport material in cured resin obtained by curing a polymerizable compound.SELECTED DRAWING: Figure 1
