Abstract
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 μm or more and 0.075 μm or less.
