Title:
ELECTROPHOTOGRAPHIC MEMBER, PROCESS CARTRIDGE AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP2018013767
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electrophotographic member capable of giving a high-quality electrophotographic image even when used as a developing member in a high temperature and high humidity environment.SOLUTION: The electrophotographic member has a conductive substrate and a conductive resin layer as a surface layer on the substrate. The surface layer comprises a urethane resin and a first polymer having a specific nitrogen-containing structure; the urethane resin has a structure derived from a second polymer containing a fluorine atom or a structure derived from a third polymer containing a fluorine atom and a silicon atom; the surface layer contains nitrogen atoms derived from the nitrogen-containing structure by a specific ratio in a region from the outer surface of the surface layer to a depth of 300 nm; and atomic ratios of nitrogen atoms, fluorine atoms and silicon atoms in a region from 100 to 300 nm depth from the outer surface of the surface layer, and in a region from the outer surface to 10 nm depth have a specific relationship.SELECTED DRAWING: Figure 1
