Patent ID: 7787785

Claim:
An image forming apparatus comprising: an image carrier; a charging device configured to charge the image carrier; an exposure device configured to form an electrostatic latent image by exposing a surface of the image carrier; a developing device configured to develop the electrostatic latent image with a toner; a controller configured to control to execute a first mode in which the surface of the image carrier charged by the charging device is exposed by the exposure device and the exposed portion is developed by the toner and a second mode in which the image carrier charged by the charging device is developed by the toner without an exposure process by the exposure device and the developed toner image is output onto a recording material; and an input device configured to input an input signal for executing the second mode, wherein the controller controls to execute the second mode under a preset image forming condition for the second mode based on the input signal from the input device, wherein, in the first mode, an absolute value of a dark portion potential of the image carrier charged by the charging device is larger than an absolute value of a DC voltage applied to the developing device and, in the second mode, the absolute value of the DC voltage applied to the developing device is larger than or equal to the absolute value of the charging potential.
