Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2023120986
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that prevents a long-term fluctuations in wear resistance of a surface protective layer.SOLUTION: An electrophotographic photoreceptor comprises: a conductive substrate that has a wall thickness of 3 mm or more; a photosensitive layer that is provided on the conductive substrate; and a surface protective layer that is provided on the photosensitive layer. The surface protective layer is a layer formed of a cured film of a composition including a reactive group-containing charge transport material having a reactive group and a charge transport skeleton in the same molecule, or a cured film of a composition including a non-reactive charge transport material and a reactive group-containing non-charge transport material not having a charge transport skeleton and having a reactive group. The ratio of the degree of cure of a surface facing the conductive substrate to the degree of cure of a surface facing an outer peripheral surface is 75% or more.SELECTED DRAWING: Figure 1
