    摘要： An electrophotographic photosensitive body has a photosensitive layer formed on a conductive substrate. The photosensitive layer contains a phthalocyanine compound as a photoconductive material, wherein the content of a phthalocyanine dimer compound in the layer that contains the phthalocyanine compound is present from about 100 nmol to about 300 mmol per 1 mol of the phthalocyanine compound. The resulting electrophotographic photosensitive body has excellent potential retention properties.

    摘要： An electrophotographic photoreceptor includes an electroconductive substrate; an undercoat layer provided on the electroconductive substrate and composed of: metal oxide fine particles including particles of at least one metal oxide and at least one organic compound provided on the particles of the at least one metal oxide as a surface treatment; and a copolymer resin synthesized by copolymerization of essential constituent monomers composed of a dicarboxylic acid, a diol, a triol and a diamine; and a photosensitive layer laminated on the undercoat layer. The undercoat layer permits (a) attaining stable electric potential characteristics in all environments ranging from low temperature and low humidity environments to high temperature and high humidity environments, (b) suppressing the occurrence of printing defects and density differences, and (c) simultaneously attaining transfer restorability and restorability from intense light-induced fatigue even in a wide variety of usages and operation environments.

    摘要： An electrophotographic photoreceptor and a manufacturing method therefore are disclosed. The electrophotographic photoreceptor includes a conductive base; and a photosensitive layer provided on the conductive base and containing a diadamantyl diester compound represented by General Formula (I) below: where, R1, R2 and R3 each independently represent a hydrogen atom, halogen atom, optionally substituted C1-6 alkyl group, optionally substituted C1-6 alkoxyl group, C6-20 aryl group or heterocyclic group, X and Z represent single bonds or optionally substituted C1-6 alkylene groups, and Y represents an OCO group or COO group. The electrophotographic photoreceptor has sufficient wear resistance and satisfactory properties as a photoreceptor, while being little affected by harmful gasses and environmental temperature and humidity.

    摘要： An electrophotographic photoreceptor includes a conductive substrate; and a photosensitive layer provided on the conductive substrate and containing a resin binder that is a polycarbonate resin having structural units represented by General Formulae (1) and (2). The electrophotographic photoreceptor reduces the amount of wear and provides good images while maintaining a low frictional resistance on the surface of a photoreceptor drum from the beginning until after printing. A method for manufacturing such an electrophotographic photoreceptor includes applying a coating liquid containing at least such a resin binder onto a conductive substrate to thereby form a photosensitive layer. An electrophotographic device is disclosed that is equipped with such an electrophotographic photoreceptor.
