Document Type and Number:
Japanese Patent JP7115116
Kind Code:
B2
Abstract:
An electrophotographic photoconductor is provided. The electrophotographic photoconductor includes a conductive substrate, a photosensitive layer, and a surface layer containing fluororesin particles, non-fluororesin particles, and a cured resin. The fluororesin particles have an average particle diameter of from 0.01 to 0.3 μm in a cross-sectional image of the surface layer as observed by a scanning electron microscope with a magnification of 5,000 times, and when the cross-sectional image is segmented into uniform regions each being 1 μm×4 μm, a standard deviation of areas each of which is occupied by the fluororesin particles and the non-fluororesin particles in each of the regions is 0.2 μm2 or less.
