Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2023048986
Kind Code:
A
Abstract:
To prevent a variation in image density in an electrophotographic photoreceptor having an inorganic protective layer even when cracks are generated in the photoreceptor due to continuous formation of images.SOLUTION: An electrophotographic photoreceptor has a conductive substrate, an undercoat layer provided on the conductive substrate, a charge generating layer provided on the undercoat layer, a charge transport layer provided on the charge generating layer, and an inorganic protective layer provided on the charge transport layer. The charge transport layer contains a binder resin and a charge transport material, and the ratio of the capacitance C1Hz at 1 Hz to the capacitance C10Hz at 10 Hz (C1Hz/C10Hz) in impedance measurement is 1.1 or less.SELECTED DRAWING: Figure 1
