Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP2023024116
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that prevents the generation of memory and maintains high contrast through the durable use.SOLUTION: An electrophotographic photoreceptor has a charge generating layer and a charge transport layer having a film thickness of 0.2 μm or more. At 23.5°C and 50%RH, when the photoreceptor is (1) made to have a surface potential of 0 V and (2) is electrified for 0.005 seconds to adjust the absolute value of the surface potential to be Vd[V], (3) the photoreceptor after the electrification is exposed with light having a wavelength of 805 nm and a quantity of light of Iexp[μJ/cm2] after 0.02 seconds from the start of electrification, and (4) the absolute value obtained through measurement after 0.06 seconds from the start of electrification is Vexp[V], in the relational expression between an electric field intensity E and a recoupling constant Pe obtained from a specific graph generated by repeatedly performing operations and measurement in (1) to (4) while changing Iexp from 0.000 to 1.000μJ/cm2 at an interval of 0.001μJ/cm2, the absolute value of the inclination α of a primary approximation straight line at an electric field intensity E of 10 to 40 V/μm is 4×10-3 or less.SELECTED DRAWING: None
