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. |

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. |
