Abstract
A charging member includes a cylindrical or columnar conductive substrate, an elastic layer provided on the conductive substrate, and a surface layer provided on the elastic layer. When in analysis of a circumferential direction period of a surface shape of the elastic layer, a maximum amplitude value in a period region of less than 5 mm is Ae, and when in analysis of a circumferential direction period of a surface shape of the surface layer, a maximum amplitude value in the period region of less than 5 mm is As, the charging member satisfies As/Ae≤0.9.
