IMAGE FORMING APPARATUS AND CARTRIDGE GROUP

摘要

In an image forming apparatus, when a line connecting a midpoint of a line segment connecting a first supporting portion and a second supporting portion and a rotational center of a first photosensitive drum as viewed from a first axial direction of the first photosensitive drum is referred to as a first straight line, and a line connecting a midpoint of a line segment connecting a third supporting portion and a fourth supporting portion and a rotational center of a second photosensitive drum as viewed from a second axial direction of the second photosensitive drum is referred to as a second straight line, the first straight line as viewed from the first axial direction and the second straight line as viewed from the second axial direction are not parallel to each other.

主权项

1. An image forming apparatus comprising:
a first photosensitive drum; a second photosensitive drum; a first drive input portion located at one end in a first axial direction of the first photosensitive drum; a second drive input portion located at one end in a second axial direction of the second photosensitive drum; a first supporting member including a first supporting portion and a second supporting portion that support a side of the one end in the first axial direction of the first photosensitive drum in such a way as to allow the first photosensitive drum to rotate; and a second supporting member including a third supporting portion and a fourth supporting portion that support a side of the one end in the second axial direction of the second photosensitive drum in such a way as to allow the second photosensitive drum to rotate, wherein, when a line connecting a midpoint of a line segment connecting the first supporting portion and the second supporting portion and a rotational center of the first photosensitive drum as viewed from the first axial direction is referred to as a first straight line, and a line connecting a midpoint of a line segment connecting the third supporting portion and the fourth supporting portion and a rotational center of the second photosensitive drum as viewed from the second axial direction is referred to as a second straight line, the first straight line as viewed from the first axial direction and the second straight line as viewed from the second axial direction are not parallel to each other.
