Provided is an electrophotographic photoreceptor including a conductive support, a photosensitive layer, and a surface protective layer disposed in sequence. The surface protective layer includes a cured product of a composition containing a polymerizable compound, a charge transporting material, and at least two polymerization initiators. The polymerization initiators include an acyl phosphine oxide and an O-acyl oxime.

Electrophotographic photoreceptor, method of producing electrophotographic photoreceptor, and apparatus of forming electrophotographic image

An imaging apparatus including: an electrophotographic photoreceptor; a charging unit to charge the surface of the electrophotographic photoreceptor; an exposing unit to perform exposure of the electrophotographic photoreceptor charged by the charging unit; a developing unit to feed a toner to the electrophotographic photoreceptor exposed by the exposing unit to form a toner image; a transfer unit to transfer the toner image formed on the electrophotographic photoreceptor; a lubricant feeding unit to feed a lubricant onto the surface of the electrophotographic photoreceptor; and a cleaning unit to remove the residual toner on the surface of the electrophotographic photoreceptor, wherein the electrophotographic photoreceptor includes a conductive support, a photoreceptive layer, and a protective layer disposed in sequence, the protective layer includes a resin containing a particulate P-type semiconductor, and the protective layer has a surface roughness Rz of 0.030 &#x3bc;m or more and 0.075 &#x3bc;m or less.
