Abstract

An image forming apparatus includes an image bearing member rotatably supported in a body of the image forming apparatus, and bearing a developer image; a developing device including a developing container, a developing member, and a transporting member, the developing container containing a developer, the developing member disposed so as to oppose the image bearing member, the developing member having thereon the developer in the developing container and rotating to develop a latent image, the transporting member transporting the developer in the developing container while stirring the developer, the developing device being unremovably supported with respect to the body of the image forming apparatus; and a damping member disposed with respect to an axial direction of a rotational axis of the developing member so as to be situated at an end portion of the developing container in the axial direction, and restraining vibration of the developing container.

Claims (13)

1. An image forming apparatus comprising:

an image bearing member rotatably supported in a body of the image forming apparatus, the image bearing member bearing a developer image on a surface thereof;

a developing device including a developing container, a developing member, and a transporting member, the developing container containing a developer, the developing member disposed so as to oppose the image bearing member, the developing member having thereon the developer in the developing container and rotating to develop a latent image formed on the surface of the image bearing member, the transporting member transporting the developer in the developing container while stifling the developer, the developing device being supported with respect to the body of the image forming apparatus; and

a damping member disposed with respect to an axial direction of a rotational axis of the developing member so as to be situated at an end portion of the developing container in the axial direction, the damping member restraining vibration of the developing container,

wherein the damping member is disposed closer to a rotational center of the developing device than the developing member when viewed from the axial direction.

2. The image forming apparatus according to claim 1 , comprising the developing container supported so as to be movable around the rotational center in directions in which the developing member moves towards and away from the image bearing member, and a biasing member that biases the developing container in a direction in which the developing member moves towards the image bearing member.

3. The image forming apparatus according to claim 2 , comprising an opposing member disposed so as to oppose the end portion of the developing container in the axial direction, and the damping member supported by one of the developing container and the opposing member, and disposed so as to be spaced apart from the other one of the developing container and the opposing member.

4. The image forming apparatus according to claim 1 , comprising an opposing member disposed so as to oppose the end portion of the developing container in the axial direction, and the damping member supported by one of the developing container and the opposing member, and disposed so as to be spaced apart from the other one of the developing container and the opposing member.

5. The image forming apparatus according to claim 1 , wherein the damping member is unaligned from the image bearing member and the developing member in the axial direction.

6. An image forming apparatus comprising:

a developing device including a developing container, a developing member, and a transporting member, the developing container containing a developer, the developing member disposed so as to oppose an image bearing member, the developing member having thereon the developer in the developing container and rotating to develop a latent image formed on the surface of the image bearing member, the transporting member transporting the developer in the developing container while stirring the developer, the developing device being supported with respect to the body of the image forming apparatus; and

a damping member disposed at an end portion of the developing device in a longitudinal direction, the damping member restraining vibration of the developing device,

wherein the damping member is disposed closer to a rotational center of the developing device than the developing member when viewed from the longitudinal direction.
