Patent number: 11927894Abstract: An image forming apparatus includes first and second image bearing members and first and second developing members. The controller controls to execute first and second controls based on image information in a case that the first developing member is separated from the first image bearing member when an operation in which the image is sequentially transferred to a transferred member from the first and second image bearing members is terminated. The first developing member is started to separate from the first image bearing member in the first control after an end of an image forming area on the first image bearing member in a moving direction passes through the first transfer position, and in the second control after the end of the image forming area on the first image bearing member in the moving direction passes through the developing position and before the end of the image forming area reaches the first transfer position.Type: GrantFiled: July 8, 2022Date of Patent: March 12, 2024Assignee: Canon Kabushiki KaishaInventors: Takao Kume, Satoshi Nishida, Isamu Takeda, Takanori Mitani
