发明名称 PROCESSING CARTRIDGE, IMAGE FORMING APPARATUS WITH SAME, AND IMAGE FORMING METHOD
摘要 An image forming apparatus includes an electrophotographic photoreceptor that bears a latent image, an electrostatic charging unit that negatively charges the electrophotographic photoreceptor uniformly with electricity, and a latent image writing unit that writes a latent image on the electrophotographic photoreceptor. A one-component developing unit renders the latent image visible by developing thereof. A transfer device transfers the toner image from the electrophotographic photoreceptor onto a transfer medium. The inequality C×V<Q≦1.5×C×V is satisfied where C is an electrostatic capacitance of the electrophotographic photoreceptor, V is an absolute value of a surface potential of the electrophotographic photoreceptor after it is electrically charged by the electrostatic charging unit in an electrostatic charging process, and Q is an absolute value of an electrical charge calculated based on an amount of electrical current sent to the electrophotographic photoreceptor in the electrostatic charging process.

主权项 1. An image forming apparatus, comprising: an electrophotographic photoreceptor to bear a latent image; an electrostatic charging unit to negatively charge the electrophotographic photoreceptor uniformly with electricity in an electrostatic charging process; a latent image writing unit to write a latent image on the electrophotographic photoreceptor electrically charged uniformly; a one-component developing unit to render the latent image visible as a toner image with one-component developer composed of toner particles; and a transfer device to transfer the toner image developed by the one-component developing unit from the electrophotographic photoreceptor to a transfer medium, wherein C×V<Q≦1.5×C×V, where C is an electrostatic capacitance of the electrophotographic photoreceptor, V is an absolute value of a surface potential of the electrophotographic photoreceptor after electrically charged by the electrostatic charging unit in the electrostatic charging process, and Q is an absolute value of an electrical charge calculated based on an amount of electrical current sent to the electrophotographic photoreceptor in the electrostatic charging process.
