Abstract
Official abstract text for this publication.
An image forming apparatus includes a main assembly, a rotatable unit, a first gear, provided in one of the rotatable unit and the main assembly, including a gear portion at an arcuate portion having a center substantially aligned with a rotation center of the rotatable unit, and a second gear, provided rotatably in another one of the rotatable unit and the main assembly, engageable with the first gear in a first rotation region of the rotatable unit. In addition, a third gear is provided at a position different from the second gear with respect to a circumferential direction of the arcuate portion and is engageable with the first gear when the rotatable unit is rotated in a second rotation region thereof. A damper mechanism imparts rotational resistance to the second and third gears when each of the second and third gears is rotated.
