  • Patent number: 8768202
    Abstract: An image forming apparatus includes a first moving member pressed and moved by an openable/closable member when the member is opened. A cartridge is switched from being positioned in an image forming position to a state where the positioning is released. A second moving member is pressed and moved by the openable/closable member when the member is opened, and the exposure member is moved from an exposure position to a retracted position. When the cartridge is released, a reaction force applied from the first moving member to the openable/closable member reaches a first peak. When the exposure member is moved to the retracted position, a reaction force applied from the second moving member to the openable/closable member reaches a second peak. Timing of the first peak is different from timing of the second peak.
