Embodiment 1

[0299] First, 100 parts by weight of zinc oxide (number-average particle diameter of 70 nm, test product manufactured by Tayca Corporation) and 500 parts by weight of toluene were mixed under agitation. Then, add 1.5 parts by weight of silane coupling agent (KBM603 TM , manufactured by Shin-Etsu Chemical Co., Ltd.), and the mixture was stirred for 2 hours. After toluene was distilled off under reduced pressure, the residue was baked at 150° C. for 2 hours.

[0300] 60 parts by weight of zinc oxide through the above surface treatment, 15 parts by weight of blocked isocyanate (Sumidule 3175 TM , manufactured by Sumitomo Byer Urethane Co., Ltd.), 15 parts by weight of butyral resin (BM-1 TM , manufactured by Sekisui Chemical Co., Ltd.) and 85 parts by weight of methyl ethyl ketone were mixed together to obtain a liquid mixture.

[0301] 38 parts by weight of the liquid mixture obtained above were mixed with 25 parts by weight of methyl ethyl ketone, and dispersed in a sand mil...

Embodiment 2

[0314] The electrophotographic photoreceptor of Example 2 was manufactured in the same manner as in Example 1 except that the thickness of the intermediate layer in Example 1 was adjusted to 19 μm.

Embodiment 3

[0316] The electrophotographic photoreceptor of Example 3 was produced in the same manner as in Example 2, except that the ten-point average surface roughness R ZJIS94 An aluminum-based material (conductive support) of 0.15 μm (formed by changing the cutting conditions in Example 2).

Abstract

An electrophotographic photoreceptor includes a conductive support; a photosensitive layer; and a surface protective layer as an outermost layer of the electrophotographic photoreceptor, wherein the electrophotographic photoreceptor satisfies following formulas (a) and (b): 3.6<=(A+B) / C x 100<=6 (a);B<=0.3 (b); wherein A (mum) represents a ten-point-averaged surface roughness RZJIS94 of the conductive support, B (mum) represents a ten-point-averaged surface roughness RZJIS94 of the surface protective layer, and C (%) represents a reflectivity of the surface protective layer against the conductive support.

Description

technical field [0001] The present invention relates to an electrophotographic photoreceptor usable as an electrostatic latent image carrier in an electrophotographic image forming apparatus, a process cartridge, and an image forming apparatus using the process cartridge. Background technique [0002] In recent years, organic photosensitive materials having photosensitive layers made of organic photoconductive materials have been mainly used as electrophotographic photoreceptors (hereinafter sometimes referred to as "photoreceptors") used in electrophotographic devices such as copiers and laser printers. , to replace inorganic photoreceptors using inorganic photoconductive materials such as selenium, selenium-tellurium alloys, selenium-arsenic alloys, and cadmium sulfide, where the organic photoconductive materials have the advantage of being relatively cheap, readily available, and disposed of at disposal It looks very advantageous. In particular, a function-separated stac...
