The present disclosure provides an electrophotographic photoreceptor including, on a conductive base, at least a photoreceptive layer or alternatively at least the photoreceptive layer and a protective layer laminated on the photoreceptive layer, in which both or either one of the photoreceptive layer and the protective layer contains a perimidine compound represented by general formula (I): (wherein X represents hydrogen atom, an alkyl group having 1 to 6 carbon atoms, or an alkoxy group having 1 to 6 carbon atoms, and m represents an integer of 1 to 6).

Electrophotographic photoreceptor, process cartridge and image-forming apparatus including electrophotographic photoreceptor

A coating liquid for an undercoat layer of an electrophotographic photoreceptor which is formed by sequentially stacking the undercoat layer and a photosensitive layer on an electrically conductive support, wherein the coating liquid comprises titanium oxide microparticles and silicon nitride microparticles as an inorganic compound, a binder resin and an organic solvent.

Electrophotographic photoreceptor, coating liquid for undercoat layer of electrophotographic photoreceptor, and method for producing the same

An electrophotographic photoreceptor comprising at least a photosensitive layer formed by laminating a charge generation layer containing a charge generation material and a charge transport layer containing a charge transport material in this order, on a conductive support, wherein the charge generation layer contains an oxotitanylphthalocyanine as the charge generation material and metal oxide microparticles, and the electrophotographic photoreceptor has photosensitive properties in light source of wavelength range from 360 to 420 nm.
