Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, ELECTROPHOTOGRAPHIC PHOTORECEPTOR CARTRIDGE, AND IMAGE FORMING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/260157
Kind Code:
A1
Abstract:
The present invention relates to an electrophotographic photoreceptor comprising at least a photosensitive layer and a protective layer in sequence on a conductive support. The electrophotographic photoreceptor is characterized in that the protective layer contains a cured product of a curable compound and at least two kinds of particles, at least one kind out of the two kinds of particles is a conductive particle with a bandgap of 2.0-3.6 eV, and at least one other kind is a particle with a bandgap of 8.0 eV or more, thereby making it possible to suppress occurrence of image deletion at the initial stage of start of printing.
