Abstract
A developing device includes a developer bearing body, a first developer supply member, a second developer supply member, and a compression member. The developer bearing body bears a developer. The first developer supply member supplies the developer to the developer bearing body. The second developer supply member moves the developer in the vicinity of the first developer supply member to the first developer supply member. The compression member opposes, and is out of contact with, the first developer supply member. The compression member also directs the developer moved by the second developer supply member to the first developer supply member, and compresses the developer between the first developer supply member and the compression member.
Claims20
A developing device comprising:
- a developer bearing body configured to bear a developer;
- a first developer supply member configured to supply the developer to the developer bearing body;
- a second developer supply member configured to move the developer in the vicinity of the first developer supply member to the first developer supply member;
- and
- a compression member that opposes, and that is out of contact with, the first developer supply member, and that is configured to direct the developer moved by the second developer supply member to the first developer supply member and compress the developer between the first developer supply member and the compression member.
An image forming apparatus comprising:
- a developing unit configured to develop an electrostatic latent image on an image bearing body with a developer to form a developed image, including
- a developer bearing body configured to bear the developer,
- a first developer supply member configured to supply the developer to the developer bearing body,
- a second developer supply member configured to move the developer in the vicinity of the first developer supply member to the first developer supply member, and
- a compression member that opposes and is out of contact with the first developer supply member, and configured to direct the developer moved by the second developer supply member to the first developer supply member and compress the developer between the first developer supply member and the compression member;
- a transfer unit configured to transfer the developed image to a medium;
- and
- a fixing unit configured to fix the developed image onto the medium.
