PROBLEM TO BE SOLVED: To accurately transmit driving force transmitted to a photoreceptor drum to other members to be driven at a low cost in a space saving state in an image forming device. SOLUTION: This image forming device is equipped with an electrifying means 34 being the member to be driven for electrifying the surface of the photoreceptor drum 2, a developing roller 21 being the member to be driven for developing an electrostatic latent image formed on the drum 2, a cleaning means 26 coming into contact with the drum 2 and removing toner remaining on the drum 2, a discharged toner carrying screw 27 being the member to be driven for carrying the toner scraped by the cleaning means 26, and a driving side flange 29b which is provided coaxially with the rotary shaft of the drum 2 at the end of the drum 2, on the inner peripheral surface of which involute spline shape to which the driving force is transmitted from a driving unit is formed, and on the outer peripheral surface of which specified gear shape to transmit the driving force to at least one member to be driven is formed. |
