PROBLEM TO BE SOLVED: To provide an image forming apparatus in which the ability to electrify a small-diameter photoreceptor is improved. SOLUTION: In addition to a corona electrifier 2, or a main electrifier, which serves as an electrifying means that electrifies a photoreceptor drum 1, a fixed magnet 15 and a rotary sleeve 14 capable of rotating around the magnet 15 are disposed in, for example, the cleaner container of a cleaning device 5. A magnetic brush is formed between the rotary sleeve and the photoreceptor drum 1, a voltage is applied to the magnetic brush, and the photoreceptor drum 1 is electrified even in the cleaner container. |
