An image-forming apparatus of an electrophotographic system equipped with an electrophotographic photoreceptor, an electrostatically charger, a light-exposure, a developing device, and a transferring device, wherein the electrophotographic photoreceptor is an electrophotographic photoreceptor having at least a charge generating layer, a charge transport layer, and an uppermost surface layer successively laminated on an electrically conductive substrate, the charge transport layer having a layer containing at least 45% by weight a charge transporting material, and the wear rate of the uppermost surface layer being less than the wear rate of said layer, and the time from a light-exposure to a development is not longer than 150 m sec. The image-forming apparatus is excellent in the printing durability and the stability, gives less image flowing, and is small-sized and high-speed.
An image-forming apparatus of an electrophotographic system comprising an electrophotographic photoreceptor, an electrostatic charger, a light-exposure, a developing device, and a transferring device, wherein said electrophotographic photoreceptor is an electrophotographic photoreceptor having at least a charge generating layer, a charge transport layer, and an uppermost surface layer successively laminated on an electrically conductive substrate, said charge transport layer having a material-containing layer containing at least 45% by weight of a charge transporting material, and wherein a wear rate of said uppermost surface layer is less than a wear rate of said material-containing layer, and a time from a light-exposure to a development is not longer than 150 m sec.
