ABSTRACT:
An image forming apparatus, and particularly an improved mounting arrangement for a developing unit of an image forming apparatus is provided. The image forming apparatus includes axis supporting members which support the axes of the developing rollers on side plates of the image forming apparatus, with each of the axis supporting members including holes which receive a respective axis of the developing rollers. In a particularly preferred form, a pair of holes are provided, one of which is in the form of a round hole or circular hole, with the other in the form of an elongated or arcuate hole or slot. The circular hole and arcuate hole are disposed such that a predetermined relationship is provided between the axis of the developing rollers and the axis of the photoconductive member, e.g., a photoconductive drum, thereby ensuring a desired gap is provided between the developing rollers and the photoconductive member, despite variations which may occur in the spacing between the axes of the developing rollers (or along the axes of the developing rollers).
