Abstract

PURPOSE:To increase the degree of freedom of design and reduce the size, weight, and cost of an image forming device and prolong the life of a photosensitive body by providing a cleaning device which recovers residual toner without contacting before the photosensitive body reaches a developing roller from an electrostatic charging device. CONSTITUTION:At the time of the photosensitive body 18 reaches the cleaning device 22, residual toner 28a at an unexposed part of the photosensitive body 18 is scattered toward a cleaning roller 31 because the DC potential difference between the unexposed part and cleaning roller 31 is 900V and recovered in a housing 30 through the rotation of the cleaning roller 31, and thus the residual toner 28a at the unexposed part is cleaned, so that the 2nd copy has no fog. Then at the time of the photosensitive body 18 reaches the developing device 23, the potential difference between the developing roller 32 and the unexposed part becomes about 330V as well as the 1st copying operation and toner 28 on the developing roller 32 is scattered to the exposed part of the photosensitive body 28, thereby performing development.
