ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE

Title:

ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE

Document Type and Number:

Japanese Patent JP2021182084

Kind Code:

A

Abstract:

To provide an electrophotographic photoreceptor that can provide a satisfactory image as an electrophotographic photoreceptor with no image defects, such as interference fringes, and can achieve high definition in an output image.SOLUTION: An electrophotographic photoreceptor has a support, a conductive layer, and a photosensitive layer in this order. The conductive layer contains a binder resin, metal oxide particles, and silica particles. The content ratio of the metal oxide particles in the total volume of the conductive layer is 20.0 volume% or more and 60.0 volume% or less. The average primary particle diameter of the metal oxide particles is 50 nm or more and 500 nm or less. The average primary particle diameter of the silica particles is 10 nm or more and 300 nm or less.SELECTED DRAWING: None
