    摘要： The invention is directed to an electrophotographic photoreceptor, and an electrophotographic cartridge and an electrophotographic imaging apparatus including the electrophotographic photoreceptor. The electrophotographic photoreceptor includes: an electrically conductive substrate; a charge generating layer formed on the electrically conductive substrate and comprising μ-oxo-gallium phthalocyanine dimer as a charge generating material dispersed in a binder resin; and a charge transporting layer formed on the charge generating layer. The charge transporting layer includes a charge transporting material and a binder resin. The charge transporting material is a combination of (1) a butadiene-based amine compound and a hydrazone compound and (2) a combination of a first benzidine compound and a second benzidine compound. The amount of the charge transporting material is 5-200 parts by weight based on 100 parts by weight of the binder resin of the charge transporting layer. The electrophotographic photoreceptor has an excellent electrostatic property and a high interlayer adhesive force and resistance to abrasion and can be manufactured at a low cost.

    摘要： Provided is a laminate type electrophotographic photoreceptor including an electrically conductive substrate, and an undercoat layer, a charge generation layer, and a charge transport layer sequentially disposed on the electrically conductive substrate, in which a characteristic response time of the photoreceptor is about 10 msec or more and about 85 msec or less and a thickness of the charge transport layer is greater than about 18 μm and equal to or less than about 45 μm. Also, an electrophotographic image forming apparatus and an electrophotographic cartridge using the electrophotographic photoreceptor are provided. An electrophotographic photoreceptor according to the present general inventive concept has an improved response time and thus, charge stain characteristics are excellent even when a thick charge transport layer is selected. Therefore, the electrophotographic photoreceptor of the present general inventive concept may have both excellent lifetime characteristics and excellent charge stain characteristics.
