PROBLEM TO BE SOLVED: To provide an image forming device capable of performing highly accurate and highly precise image formation by reducing the irregular rotation with a simple constitution. SOLUTION: This image forming device is capable of reducing the irregular rotation with a simple constitution by fixing a peripheral section of a reinforcing plate 1c whose rigidity is higher than teeth part 1f to the teeth part 1f while extending to the outside of the teeth bottom circle 1e of a gear edge surface 1b on at least, one of several gear composing a photoreceptor driving system, and adopting the vibration proof gear 1 composed in holding an elastic member 1i in close contact with the inside of the teeth bottom circle 1e of the gear edge surface 1b by the reinforcing plate 1c. |
