PROBLEM TO BE SOLVED: To reduce the diameter size of a transmission gear engaging with a motor gear and to reduce the thickness of the gear. SOLUTION: The image forming device is provided with several photoreceptor drums for forming each electrostatic latent image corresponding to each color toner image, a developing roller for developing the electrostatic latent image formed on each photoreceptor drum, a 1st transmission gear 18 and a 2nd transmission gear 19 separately engaging with a motor gear 17 attached to the shaft of the motor, a 1st transmission system 20 for transmitting the rotating force of the motor transmitted to the 1st transmission gear 18 to the photoreceptor drums for forming the electrostatic latent images corresponding to yellow and magenta toner images and the corresponding developing rollers, and a 2nd transmission system 21 for transmitting the rotating force of the motor transmitted to the 2nd transmission gear 19 to the photoreceptor drum for forming the electrostatic latent image corresponding to the cyan toner image and the corresponding developing roller. |
