[origin: EP0436306A2] An image forming apparatus for forming a toner image on a peripheral surface of an image carrying drum (10) and transferring the toner image onto a recording paper. The image forming apparatus comprises a conveyor (71) to convey the recording paper, a register roller (79) to feed the same to the conveyor (71), transfer unit (70) for transfering the toner image and a pre-charging unit (60) for charging the recording paper before the transferring.
