PROBLEM TO BE SOLVED: To improve image quality by reducing vibration transmitted to a photoreceptor. SOLUTION: As for a photoreceptor driving mechanism 70 for driving the photoreceptor, constitutional parts such as a motor, a gear mechanism 74, photoreceptor driving shafts 75B, 75C, 75M and 75Y, etc., are mounted on metallic supporting plates 71 and 72 which are connected each other, and then, the mechanism is integrated as a photoreceptor driving unit 77. As for a developing driving mechanism 80 for driving the developing device, constitutional parts such as a motor, 83, a gear mechanism 84, developing driving shafts 85C, 85M and 85Y etc., are mounted on metallic supporting plates 81 and 82 which are connected each other, then, the mechanism is integrated as a developing driving unit 88. The photoreceptor driving unit 77 and the developing driving unit 88 are individually mounted on a resin main body frame 90. Since the photoreceptor driving unit 77 and the developing driving unit 88 are separately constituted, the vibration transmitted to the photoreceptor is reduced. |
