Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, PROCESS CARTRIDGE, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
Japanese Patent JP2022140250
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that achieves suppression of both toner slipping and toner fusion in a high temperature and high humidity environment.SOLUTION: On a photoreceptor having wrinkles in an outer surface, square observation areas of one side 300 μm are placed which take, as center points, 76 intersections of 19 line segments dividing the outer surface into 20 equal parts in an axial direction and four line segments dividing the outer surface into four equal parts in a circumferential direction, and when a line passing through the center point and parallel to the circumferential direction is a first reference line L1, and reference lines obtained by rotating the L1 by 0.1° are L2-L1800, a linear shape part parallel to any one of L1-L150 and L1651-L1800 and having a length of 50 μm or more is present in a convex part of the wrinkle. Each of L1-L1800 intersects with the convex part at a plurality of portions, and at least two of the portions have intersection angles different from each other. When frequency analysis is performed on height information on the wrinkle to obtain a two-dimensional power spectrum, a one-dimensional radial distribution function has at least one maximum value. When an angle distribution is calculated from the spectrum at a frequency of the maximum value, a power value has a specific relationship.SELECTED DRAWING: Figure 1
