Abstract
An image forming apparatus includes a photosensitive member; a charging member, an exposure member, a developing member, a transfer member, a moving member, a motor, a first drive transmitting portion, and a second drive transmitting portion. A rotation amount of the motor when the photosensitive member rotates from an exposure position to a transfer position during image formation is 2πn+η [rad] where n is a natural number, and η is an increased rotation amount [rad] of the motor. The following relationship is satisfied: 0<η<π−Φ where Φ is an angle [rad] which is formed by a line connecting rotation centers of a first gear of the motor and a second gear of the first driving transmitting portion and a line connecting rotation centers of the first gear of the motor and a third gear of the second driving transmitting portion.
