Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP2020071478
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that prevents variation in electrification potential after long-period repeated use under a low humidity environment.SOLUTION: An electrophotographic photoreceptor has a support, an undercoat layer, a charge generation layer containing a charge generation material and a binder resin, and a charge transport layer containing a charge transport material and a binder resin in this order. The charge generation material contained in the charge generation layer is chlorogallium phthalocyanine that shows diffraction peaks at 7.4°, 16.6°, 25.5°, and 28.3° Bragg angles (2θ±0.2°) in an X-ray diffraction pattern using CuKα rays. The undercoat layer contains a strontium titanate particle and binder resins.SELECTED DRAWING: None
