Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP2022189754
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that can achieve both an improvement in image quality of a halftone image and an improvement in transfer property by preventing scattering of light on a surface layer of the electrophotographic photoreceptor.SOLUTION: An electrophotographic photoreceptor has a support and a photosensitive layer on the support. A surface layer of the electrophotographic photoreceptor contains particles. The surface layer has particles that are partially exposed from the surface layer among the particles contained in the surface layer. The volume average particle diameter of the particles is 50.0 nm or more and 350.0 nm or less. In a cross section of the surface layer, the number of the particles partially exposed from the surface layer is 80 number% or more based on the total number of the particles contained in the surface layer. The sum of the volume of exposed parts of the particles partially exposed from the surface layer is 30 volume% or more and 80 volume% or less based on the total volume of the particles contained in the surface layer.SELECTED DRAWING: None
