Electrophotographic member having a surface layer with a cross-linked urethane resin-containing matrix, process cartridge, and apparatus
Abstract:
The electrophotographic member includes: an electroconductive substrate; and a surface layer having a mono-layer structure, wherein the surface layer has a matrix containing a cross-linked urethane resin as a binder, and when an elastic modulus of the matrix in a first region in a thickness direction from an outer surface of the surface layer to a depth of 0.1 μm from the outer surface of the surface layer is defined as E1, and an elastic modulus of the matrix in a second region in a thickness direction from a depth of 1.0 μm from the outer surface of the surface layer to 1.1 μm from the outer surface of the surface layer is defined as E2, E1 and E2 satisfy the following Expressions (1) and (2), respectively: E1≥200 MPa  (1); and 10 MPa≤E2≤100 MPa  (2).
