PURPOSE:To provide an image forming device capable of excellently maintaining cleaning properties even if the quantity of toner inputted to a cleaning blade cleaning a transfer rotary body is changed. CONSTITUTION:When an actual toner image on a photosensitive drum 14 is transferred on a transfer paper, a cleaning device 26 having the cleaning blade 42 is arranged opposite to a transfer belt 21 carrying the transfer paper. When the transfer ratio of the toner from the photosensitive drum 14 to the transfer belt 21 is high, a cleaning blade press-contact force variable device is constituted to connect with the cleaning blade 42, so that the press-contact force of the cleaning blade 42 with the transfer belt 21 is increased. |
