PROBLEM TO BE SOLVED: To obtain a recorded image with desired density regardless of the unstable electrified state of a photoreceptor at the beginning of the starting time of an image forming action and to prevent a ghost image caused by the unstable electrified state from being formed in the recorded image. SOLUTION: This image forming device is provided with the turning photoreceptor drum 1, a main electrifier 2 initially electrifying the drum 1, an ROS 3 exposing the drum 1 electrified by the electrifier 2 according to image information, a developing unit 4 forming a toner image by developing an electrostatic latent image formed on the drum 1 and a second electrifier 5 or 7 disposed on a more downstream side than the unit 4 and on a more upstream side than the electrifier 2 in the rotating direction of the drum 1 and set for electrifying or discharging the drum 1 Besides, it is provided with a preliminary electrification control means preliminarily electrifying the drum 1 by the electrifier 5 or 7 in a fixed time immediately after the drum 1 is started to be rotated before it is initially electrified by the electrifier 2. |
