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.
