Abstract
A developing unit and an image forming apparatus are disclosed. The developing unit includes an image carrier on which an electrostatic latent image is formed, a developing member to supply a developer to the image carrier, and a first cleaning member having a first cleaning blade to remove a non-transferred developer on the image carrier. The first cleaning blade is configured to be reversible between a counter disposition, which is opposite to a rotation direction of the image carrier while the image carrier is in a printing operation, and a trailing disposition, which corresponds to the rotation direction.
Claims20
A developing unit, comprising:
- an image carrier on which an electrostatic latent image is formed;
- a developing member to supply a developer to the image carrier;
- and
- a first cleaning member having a first cleaning blade to remove a non-transferred developer on the image carrier,
- wherein the first cleaning blade is configured to be reversible between a counter disposition and a trailing disposition which are opposite to each other with respect to a reference surface of the image carrier.
A developing unit, comprising:
- an image carrier on which an electrostatic latent image is formed;
- a charging member to charge a surface of the image carrier with electricity;
- a developing member to supply a developer to the image carrier;
- a cleaning member having a cleaning blade to remove a non-transferred developer on the image carrier and a bracket for supporting the cleaning blade;
- and
- an electricity removing member to emit a light to the image carrier to remove an potential on the surface of the image carrier,
- wherein the bracket comprises a reflection material disposed at a side surface thereof to reflect at least a portion of the light emitted from the electricity removing member toward the surface of the image carrier.
An image forming apparatus having a developing unit, the developing unit comprising:
- an image carrier on which an electrostatic latent image is formed;
- a developing member to supply a developer to the image carrier;
- and
- a first cleaning member having a first cleaning blade for removing a non-transferred developer on the image carrier,
- wherein the first cleaning blade is configured to be reversible between a counter disposition, and a trailing disposition disposed opposite to the counter disposition with respect to a reference surface of the image carrier in a printing operation.
