ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE

WIPO Patent Application WO/2024/085019

A1

Provided is an electrophotographic photoreceptor that achieves good transferability.　This electrophotographic photoreceptor has a surface layer containing a binder resin and particles, and is characterized in that: each of the particles is an organic-inorganic composite particle; the organic-inorganic composite particle has a resin particle and inorganic fine particles present in a state of being embedded partially in the resin particle; small projections A derived from the inorganic fine particles are present in the surface of the organic-inorganic composite particle; a large projection derived from the organic-inorganic composite particle is present in the surface of the surface layer; the height of the large projection is 70-250 nm; small projections B derived from the small projections A are present in the surface of the large projection; and the radius of curvature of the small projections B is 10-30 nm.
