Patent ID: 8420284

Claim:
An electrophotographic photoreceptor, comprising: an electroconductive substrate; a photosensitive layer, located overlying the electroconductive substrate; and an outermost layer including a plurality of convexities that are located overlying the photosensitive layer and are independent each other, wherein each of the outermost layer and the convexities includes a crosslinked body including a structural unit having a triarylamine structure, wherein the crosslinked body is formed by crosslinking a coating liquid comprising a compound having the following formula (1): and wherein each of d, e and f is 0 or 1; each of g and h is 0 or an integer of from 1 to 3; R 13 represents a hydrogen atom or a methyl group; each of R 14 and R 15 represents an alkyl group having from 1 to 6 carbon atoms, wherein when g is 2 or 3, the groups R 14 may be the same as or different from each other, and when h is 2 or 3, the groups R 15 may be the same as or different from each other; Z represents a methylene group, an ethylene group or one of the following groups: and j is 0 or 1; and wherein the number of the convexities having a height not less than ½×RzJIS is from 30 to 300 in a measurement length of 12 mm, wherein RzJIS is an average of ten-point mean roughness and measured at least 4 random positions in an area the outermost layer is formed on, and wherein for each specific convexity of the convexities, the height of the specific convexity is a distance from the deepest valley to a top of the convexity in the measurement length of 12 mm wherein the height of the convexity is greater than 1.5 μm and no more than 6 μm.
