Abstract
The image forming apparatus includes a movable image bearing member, a charging member opposed to the image bearing member in a charging portion, a transfer member for transferring an image formed on the image bearing member to a transferred member, and a cleaning mode for applying a voltage to the transfer member, and when other area on the image bearing member differing from a surface potential changing area on the image bearing member which is changed in surface potential by the application of this voltage is located in the charging portion, applying a voltage to the charging member, thereby cleaning the transfer member and the charging member. Thereby, the cleaning of the charging member can be effected well.
Claims10
An image forming apparatus having:
- a movable image bearing member;
- a charging member opposed to said image bearing member in a charging portion;
- a transfer member for transferring an image formed on said image bearing member by a developer to a transferred member;
- and
- a cleaning mode for applying a voltage to said transfer member, and when other area on said image bearing member differing from a surface potential changing area on said image bearing member which is changed in surface potential by the application of this voltage is located in said charging portion, applying a voltage to said charging member, thereby cleaning said transfer member and said charging member.
