Document Type and Number:
Japanese Patent JP2022132142
Kind Code:
A
Abstract:
To provide an electrophotographic photoreceptor that can prevent unevenness in a surface direction of an output image through repeated image formation.SOLUTION: In an electrophotographic photoreceptor having a cylindrical support and a photosensitive layer formed on the support, the support contains at least one of aluminum and an aluminum alloy. When A(μm2) is the area at the maximum frequency calculated from an area distribution curve of crystal grains of aluminum on a surface of the support, and B(μm2) is the half width of the maximum peak in the area distribution curve, the support satisfies the following formula (1). (1) B/A≤1.0.SELECTED DRAWING: Figure 1
