Abstract
An objective is to provide an electrophotographic photoreceptor having a protective layer in which no unevenness is generated in a coated layer even though a coating solution containing a large addition amount of metal oxide is coated, mechanical strength of a protective layer is high; productivity is high with long life of the coating solution because of no sedimentation of metal oxide, electrical resistivity and mechanical strength are satisfactory, and metal oxide generating no coated layer defect together with no light scattering caused by dispersion failure is dispersed, and also to provide an image forming method and an image forming apparatus employing the electrophotographic photoreceptor. Also disclosed is an electrophotographic photoreceptor possessing a conductive support, at least a photosensitive layer and a protective layer, wherein the protective layer comprises rutile type titanium dioxide and anatase type titanium dioxide.
