Abstract

A photosensitive unit configured to be mounted in a main frame of an image forming apparatus along a prescribed direction. The image forming apparatus includes a pressure unit, a first positioning portion, and a second positioning portion. The photosensitive unit includes a plurality of photosensitive drums, a pair of metal plates, and a resin frame. The pair of metal plates is spaced away from each other in the axial direction of each photosensitive drum and supports the plurality of photosensitive drums. The pair of metal plates is configured to be positioned on the second positioning portion. The resin frame supports the pair of metal plates and is configured to support a plurality of developer cartridges. The resin frame is configured to be positioned on the first positioning portion. The pair of metal plates is pressed against the second positioning portion to be positioned with respect to the main frame when the resin frame is pressed by the pressure unit in the prescribed direction.

Description

technical field [0001] The present invention relates to a photosensitive unit supporting a plurality of photosensitive drums and an image forming apparatus provided with the photosensitive unit. Background technique [0002] A tandem type color printer known in the prior art includes a main frame and a photosensitive unit. The photosensitive unit integrally supports a plurality of photosensitive drums, and is slidably movable relative to the main frame. More specifically, the photosensitive unit of this technology includes: a pair of metal plates, a positioning shaft, and a pair of resin frames. A pair of metal plates is used to support the plurality of photosensitive drums at shaft ends of the photosensitive drums so that the plurality of photosensitive drums are located between the pair of metal plates. Each of the pair of metal plates has a front end portion (an end portion downstream of the other end portion in the mounting direction) formed with a cutout portion. The...
