Abstract
An electrophotographic photoconductor includes a conductive substrate, and a photoconductive layer, in which an outermost surface layer contains a binder resin, a charge transporting material, fluorine-containing resin particles, and an acidic compound, the number of carboxyl groups in the fluorine-containing resin particles is 0 or more and 30 or less per 10carbon atoms of the fluorine-containing resin particles, and in a case where charging and exposure of the electrophotographic photoconductor are repeated 10,000 times under conditions of a charging potential of −700 V and an exposure intensity of 5 mJ/m, an absolute value |RP−RP| of a difference between a residual potential RPafter charging and exposure once and a residual potential RPafter charging and exposure 10,000 times is 25 V or less.
