PROBLEM TO BE SOLVED: To reliably transmit driving, and to easily pull out an image carrying rotary body from a motive power source. SOLUTION: A magnet 22 is installed on a motive power shaft 23 of a motor 24, an iron flange 21 is arranged on the side surface of a photoreceptor drum 1, and an image is formed in a state where these attract each other. A radius R is enlarged so that the relationship being (R>=T/F) is realized between the radius R of the magnet 22, attraction force F and load torque T of the photoreceptor drum 1. Thus, while easily pulling out an imaging unit 28 containing the photoreceptor drum 1, the occurrence of a slide is prevented in driving the photoreceptor drum 1. |
