Image forming apparatus including resin frame for supporting image forming units having photosensitive members

摘要

An image forming apparatus includes a plurality of image forming units in an arrangement direction orthogonal to a rotary axis thereof; a support member configured to support the plurality of image forming units; a frame, which is configured to support the support member, and a plurality of electrodes, which is supported to the frame and is configured to supply power to the plurality of image forming units, wherein the frame comprises: a plurality of support projections, which protrudes inwardly to support the plurality of electrodes, and a projection part, which is arranged at an outer position of the plurality of support projections, at which the projection part overlaps with the support member, as viewed from the direction of the rotary axis, and is contactable to the support member in a case where the support member is moved towards the frame.

1. An image forming apparatus comprising:
a plurality of image forming units respectively having a photosensitive drum rotatable about a rotary axis and arranged side by side in an arrangement direction orthogonal to the rotary axis; a support member configured to support the plurality of image forming units; a frame, which is made of resin, is arranged at one end-side of the photosensitive drum in a direction of the rotary axis and is configured to support the support member; a first beam member, which is made of metal, has a long shape extending in the orthogonal direction, is arranged along an outer surface of the frame and is fixed to the frame; and a plurality of electrodes, which is supported to the frame and is configured to supply power to the plurality of image forming units, wherein the frame comprises:
a plurality of support projections, which protrudes inwardly from an inner surface of the frame and is configured to support the plurality of electrodes, anda projection part, which is arranged at an outer position of the plurality of support projections, at which the projection part overlaps with the support member, as viewed from the direction of the rotary axis, and is contactable to the support member in a case where the support member is moved towards the frame.
