Abstract:
An image forming apparatus includes a control portion configured to perform a cleaning operation including: a first step of causing a developer, which has a reversed polarity and is attracted to a surface of a charging roller, to have a normal polarity under a state in which the developer bearing member is separated from the image bearing member with the contact/separation unit; and a second step of collecting the developer, which has the normal polarity and is attracted to the surface of the image bearing member, to the developer bearing member, by rotating the image bearing member and the developer bearing member under a state in which the developer bearing member is brought into contact with the image bearing member with the contact/separation unit after performing the first step.

Claim (Index 33):
An image forming apparatus, comprising:\n an image bearing member; a charging roller configured to charge a surface of the image bearing member through contact with the surface at a charging position; a developer bearing member configured to bear a developer and supply the developer having a normal polarity onto the surface of the image bearing member at a developing position when being in contact with the image bearing member, to form a developer image; a developer container replaceable without replacing the charging roller and configured to contain the developer to be supplied to the developer bearing member; a transfer member configured to transfer the developer image to a transferred member at a transfer position, the developer bearing member being capable of collecting the developer remaining on the surface of the image bearing member after passing through the transfer position; and a control portion configured to perform a cleaning operation for the charging roller based on replacement of the developer container.
