Abstract

The present invention provides an image forming apparatus including: a first moving member pressed and moved by an openable/closable member when the openable/closable member is opened, and switching a cartridge from a state where the cartridge is positioned in an image forming position to a state where the positioning is released; and a second moving member pressed and moved by the openable/closable member when the openable/closable member is opened, and moving the exposure member from an exposure position to a retracted position, wherein when the positioning of 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, and timing of the first peak is different from timing of the second peak.

First claim

1 - 12 . (canceled)

13 . 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:
an operation member that moves to a first position and a second position with respect to a main body of the apparatus; an 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; 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; and a 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, the exposure member being within the main body of the apparatus when the exposure member is in the retracted 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, and wherein, 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.
