Abstract:
A charging member includes a conductive base material and a conductive outermost layer provided on the conductive base material, wherein the conductive outermost layer has a ten-point average surface roughness Rz of 2 μm to 20 μm and contains a resin and particles in which particles having a particle diameter of 5.0 μm or more and a circularity of 0.8 or less are 30% by number or less with respect to the total number of particles having a particle diameter of 5.0 μm or more and particles having a particle diameter of less than 5.0 μm and a circularity of 0.8 or less are from 20% by number to 80% by number with respect to the total number of particles having a particle diameter of less than 5.0 μm.
