PROBLEM TO BE SOLVED: To prevent a development ghost from remaining on a developing sleeve after development and resulting in a ghost image in a print image. SOLUTION: The device is composed so as to perform development by forming a thin layer of one-component insulating developer on a developing sleeve 131. In this case, a discharging roller 135 comprising an elastic roller is abutted, via the developer, against the developing sleeve 131 after development and an oscillating electric field is generated between the developing sleeve 131 and discharging roller 135, thereby discharging the developer or developing sleeve 131 by AC discharging. |
