Abstract
The image forming member has a frame member which forms the image forming member, the frame member including: a first support member, the first support member having a first member and a second member which is attached to the first member, a part of the second member being outside of the first member in a longitudinal direction of the first support member, a second plate member being fixed to a first plate member so that a length of the first support member in a longitudinal direction becomes a predetermined length; a second support member which is fastened to the first plate member by welding; and a third support member which is fastened to the second plate member by welding. Thereby, the image forming member can form images with high accuracy.
Claims23
An image forming apparatus comprising:
- an image forming unit;
- and
- a frame configured to support the image forming unit, the frame including:
- a first column member;
- a second column member;
- and
- a connecting unit connecting the first column member and the second column member, the connecting unit including:
- a first member having a welding surface that (i) is disposed on a portion of the first member closer to one end of the connecting unit than a center of the connecting unit in a longitudinal direction of the connecting unit, (ii) faces a part of the first column member and (iii) is welded to the part of the first column member;
- and
- a second member fixed to the first member, the second member having a welding surface that (i) is disposed on a portion of the second member closer to another end of the connecting unit than the center of the center of the connecting unit in the longitudinal direction of the connecting unit, (ii) faces a part of the second column member, and (iii) is welded to the part of the second column member, the second member being fixed to the first member to set a length between the welding surface of the first member and the welding surface of the second member in the longitudinal direction, the length being set so that a distance between the first column member and the second column member is a predetermined distance.
