AI Technical Summary
Technical Problem
In high temperature and high humidity environments, the friction between the cleaning blade and the photosensitive component increases, causing the toner to slip or melt and bond, affecting image quality.
Method used
A textured structure with a specific pleated shape is set on the surface of the photosensitive component. The arrangement of the protrusions is designed by frequency analysis and two-dimensional power spectrum to reduce friction and disperse toner pressure.
Benefits of technology
It effectively inhibits toner slippage and melting, improves cleaning performance, and ensures image quality stability under high temperature and high humidity environments.

Abstract
This invention relates to an electrophotographic photosensitive element, a processing cartridge, and an electrophotographic apparatus. In the electrophotographic photosensitive element, a fold has a protrusion with a straight-shaped portion having a length of 50 μm or more. This straight-shaped portion is parallel to any one of L1 to L150 and L1651 to L1800, and L1 to L1800 intersect the protrusion at multiple locations, with at least two locations having different intersection angles. Furthermore, when frequency analysis is performed on the height information of the fold to obtain a two-dimensional power spectrum, a one-dimensional radial distribution function has at least one maximum value, and when the angular distribution is calculated from this spectrum at the frequency of the maximum value, the power values exhibit a specific relationship.
