Image forming apparatus

An image forming apparatus in which a cartridge that supports a photosensitive member is mounted to an image forming position, and which forms a latent image on the photosensitive member by exposure to form an image, the apparatus comprising:nan exposure member that (i) includes a light emitting element arranged in an array and (ii) exposes the photosensitive member of the cartridge located in the image forming position when the exposure member is in an exposure position;an operation member that moves to a first position and a second position with respect to a main body of the apparatus;a first moving member that is pressed and moved by the operation member when the operation member is moved from the first position to the second position, and switches the cartridge from a state where the cartridge is positioned in the image forming position to a state where the positioning is released; anda second moving member that is pressed and moved by the operation member when the operation member is moved from the first position to the second position, and moves the exposure member from the exposure position to a retracted position where the exposure member is more retracted from the photosensitive member than the exposure position,wherein, while the operation member is moved from the first position to the second position to switch the cartridge from the state where the cartridge is positioned to the state where the positioning is released, a first force acts from the first moving member to the operation member in a direction in which the moving of the operation member from the first position to the second position is suppressed, andwherein, while the operation member is moved from the first position to the second position to move the exposure member from the exposure position to the retracted position, a second force acts from the second moving member to the operation member in a direction in which the moving of the operation member from the first position to the second position is suppressed, and wherein, while the operation member is moved from the first position to the second position, timing of a peak of the first force is different from timing of a peak of the second force.

An image forming apparatus in which a cartridge that supports a photosensitive member is inserted into a main body of the apparatus in an insertion direction along a longitudinal direction of the cartridge and mounted to an image forming position inside the main body of the apparatus, and which forms a latent image on the photosensitive member by exposure to form an image, the apparatus comprising:nan exposure member that (i) includes a plurality of light emitting elements arranged in an array and (ii) exposes the photosensitive member of the cartridge located in the image forming position by the plurality of light emitting elements when the exposure member is in an exposure position, the exposure member being movable to a retracted position where the exposure member is more retracted from the photosensitive member than the exposure position;an operation member that moves to a first position and a second position with respect to the main body of the apparatus;a first moving member that moves the cartridge to the image forming position by moving the cartridge in a direction different from the insertion direction when the cartridge is mounted to the main body of the apparatus; anda second moving member that moves the exposure member from the retracted position to the exposure position as the operation member is moved from the second position to the first position.
