## Abstract

Disclosed is a developing apparatus including: a developer bearing member that bears a developer; a developing frame body that rotatably supports the developer bearing member; a one-end side end member that supports one-end side in an axis direction of the developer bearing member of the developing frame body; and another-end side end member that supports the other-end side in the axis direction of the developer bearing member of the developing frame body. Each of the one-end side end member and the other-end side end member is independently movable with respect to the developing frame body.

## Claims

### Claim 1

A developing apparatus comprising:
a developer bearing member;
a developing frame body that rotatably supports the developer bearing member;
a one-end side end member that supports one end of the developing frame body in an axis direction of the developer bearing member; and
another-end side end member that supports the other end of the developing frame body in the axis direction of the developer bearing member, wherein
each of the one-end side end member and the other-end side end member is independently rotatable with respect to the developing frame body.

### Claim at position 2

2-30. (canceled)
