The invention provides an electrophotographic photoreceptor, which undergoes little abrasion over long term use and is able to develop a stable image, as well as a method of producing the same and an electrophotographic device including the same. The electrophotographic photoreceptor includes a conductive substrate; and a photosensitive layer that contains an inorganic oxide and that is formed on the conductive substrate from a coating liquid. A test slurry containing 20% by mass of the inorganic oxide dispersed in a solvent for forming the coating liquid has a light transmittance of 40% or more in a test case where light having a wavelength of 780 nm irradiates the test slurry.

The invention relates to a multilayer type electrophotographic photoreceptor comprising: a conductive support; and, on the conductive support, a charge generation layer containing a hydroxygallium phthalocyanine pigment and a charge transport layer, wherein the content of -chloronaphthalene in hydroxygallium phthalocyanine pigment in the charge generation layer is in a range of 0 ng/cm.sup.2 to 0.1 ng/cm.sup.2, the charge transport layer contains a non-halogen organic solvent having a boiling point of 140 C. or more, and the content of the non-halogen organic solvent having a boiling point of 140 C. or more is in a range of 0.1 g/cm.sup.2 to 5 g/cm.sup.2.

Provided is an electro-conductive belt including an electro-conductive resin layer. The electro-conductive resin layer includes a matrix containing a thermoplastic resin having at least one bond selected from the group consisting of an amide bond, an ester bond and a carbonate bond, a domain containing an ionic liquid containing a hexafluorophosphate anion or an anion expressed by formula (1), and particles containing a silicone resin having a structure expressed by formula (2): R.sub.0SiO.sub.3/2. Formula (1) ##STR00001##

An electrophotographic photoreceptor includes a conductive substrate, an organic photosensitive layer on the conductive substrate, and an inorganic protective layer on the organic photosensitive layer. A layer that constitutes a surface of the organic photosensitive layer contains a charge transport material, a binder resin, silica particles, and a silicone compound.
