Abstract: An image forming apparatus includes image forming unit, frame structure, a plurality of rotational shafts, a plurality of drive gears, resin drive housing, and high voltage substrate. The frame structure includes at least one metal side plate frame having inner side surface facing internal space that accommodates the aforementioned unit and outer side surface opposite the inner side surface. The plurality of drive gears each rotate about an axis of the rotational shaft. The drive housing includes supporting side surface that supports one end of the rotational shaft and cavity in which the plurality of drive gears is accommodated, and the drive housing is open at the other end of the rotational shaft. The drive housing includes substrate supporting portion that supports the high voltage substrate, and is attached to the side plate frame such that the opening is sealed by the inner side surface of the side plate frame.

Abstract: An image forming apparatus includes a drive unit, an image bearing member, a developing unit, a support unit, an urging member, and a switching mechanism. The urging member generates an urging force for pivoting the support unit in an approaching direction in which a peripheral surface of a developing roller is moved toward a peripheral surface of the image bearing member. The switching mechanism switches the support unit between a first position (fitting position) and a second position (releasing position). The support unit includes: a second drive input section disposed coaxially with a pivot shaft and for receiving a rotational drive force from a drive output shaft of the drive unit; and a transmission mechanism for transmitting the rotational drive force to a first drive input section. The rotation direction of the rotational drive force is for rotation in a direction of pivoting the support unit in the approaching direction.
