Abstract

An image forming apparatus includes a first frame member and a second frame member which are aligned in a direction of a rotation axis of an image bearing member and faces each other across an image forming unit and a stacking unit. The first frame member includes a first portion including a first side surface facing the image forming unit and a second portion, which is fixed to the first portion, including a second side surface facing the stacking unit. The second frame member includes a third side surface facing the image forming unit and the stacking unit, and at least a part of the second side surface is provided in a position different from a position of the first side surface in the direction of the rotation axis of the image bearing member.

Claims

1-1. mage forming apparatus according to claim 1, wherein the first portion supports an image bearing member driving unit configured to drive the image bearing member.

18. An image forming apparatus comprising:

an image forming unit configured to transfer a toner image formed on an image bearing member onto a recording medium;

a stacking unit on which a recording medium to be conveyed to the image forming unit is stacked; and

a first frame member and a second frame member which are aligned in a direction of a rotation axis of the image bearing member and face each other across the image forming unit and the stacking unit,

wherein the first frame member includes a first portion and a second portion, the first portion including a first side surface facing the image forming unit, the second portion being provided separately from the first portion and including a second side surface facing the stacking unit, and the second portion is fixed to the first portion,

wherein the second frame member includes a third side surface facing the image forming unit and the stacking unit, the first portion is formed of a metal, and the second portion is formed of a resin, and

wherein at least a part of the second side surface is provided in a position different from a position of the first side surface in the direction of the rotation axis of the image bearing member.
