Process cartridge for image forming apparatus

At ends of a frame in an axial direction of a developing roller, a first end portion member and a second end portion member are provided so as to be rotatable around a rotation axis parallel to the axial direction, and at least one of them has one side in a direction orthogonal to the rotation axis on which a force receiving portion is provided, and another side in the direction orthogonal to the rotation axis on which a regulating portion is provided. The force receiving portion receives a biasing force in a mounting direction of the developing apparatus to the apparatus main body from a biasing member. The regulating portion is brought into contact with the apparatus main body to regulate movement of the other side relative to the apparatus main body in a direction opposite to the mounting direction, with a fulcrum being the rotation axis.

Developing apparatus and image forming apparatus

A second conveying member is disposed upstream of a first conveying member in a rotation direction of a conveyance shaft in a state in which a fixed end of the second conveying member and a fixed end of the first conveying member overlap each other. In a first position, a second position, and a third position that sequentially distance away from a drive transmission member in an axial direction of the conveyance shaft, a free end of the first conveying member and a free end of the second conveying member sequentially becomes larger as well.
