An image forming apparatus includes a frame structure including first and second frames supporting a photosensitive member, and a third frame extending in the axis direction and connecting the first frame and the second frame with each other; an operating portion for receiving an instruction of a user; a supporting portion rotatably supporting the operating portion; and a connecting portion connecting the supporting portion with the first frame and the third frame, the connecting portion including a first fixed portion fixed to the third frame, a contact portion contacted with the first frame to restrict movement at least in a direction while permitting movement in another direction, and a second fixed portion fixed to the first frame at a position closer to the first fixed portion than to the contact portion.

Image forming apparatus with an operating portion connected to a frame of the image forming apparatus

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.
