PROBLEM TO BE SOLVED: To realize high image quality in an output image and a long service life in an image forming device by keeping down wear of an image carrier 1 and an electrifying member 2-A-a without affecting an image formation in a type of the image forming device where an injection electrifying system is especially utilized as an electrifying means 2 of the image carrier 1. SOLUTION: In the device, a process where a difference in circumferential speed of rotation of the electrifying member 2-A-a against the image carrier 1 is smaller than the difference in the circumferential speed in an electrifying process in a process that is other than a process of image formation in the image carrier 1 and a process where contact pressure of the electrifying member 2-A-a against the image carrier 1 is smaller than the contact pressure at the electrifying process are provided. |
