  • Patent number: 10866533
    Abstract: An image forming apparatus using a contact charging method includes a control unit capable of executing cleaning in a post-rotation step at the end of a job and in an inter-image step during execution of the job. The cleaning involves moving toner adhering to a charging member from the charging member to an image bearing member. The job is a series of operations started by a predetermined start instruction and involving forming an image on one or more recording materials and outputting the one or more recording materials. When an instruction to start the next job is input during execution of cleaning in the post-rotation step, the control unit stops the cleaning in the middle of the execution, starts the next job, and adjusts timing for executing subsequent cleaning on the basis of information relating to the amount of cleaning executed before being stopped in the middle of the execution.
