摘要： 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.

摘要： A biasing member is configured to provide a pressing member with a biasing force acting to bias the pressing member against a detecting portion before the pressing member receives a reaction force from the detecting portion when an opening/closing member is closed. A support portion receives the reaction force acting on the pressing member from the detecting portion while the opening/closing member is closed, and the pressing member maintains an operation state independently with respect to the detecting portion while the opening/closing member is closed.

摘要： An image forming apparatus for forming an image on a recording material by exposing a photosensitive member with a light emitting member in a state where a cartridge including the photosensitive member is mounted in an apparatus main body includes a light emitting member, a support member, and a duct formed in the support member. The light emitting member includes a plurality of light emitting portions arranged in an array. The support member supports the light emitting member. The duct forms an air supply path extending in a longitudinal direction of the cartridge to cool the cartridge mounted in the apparatus main body.

摘要： A detection unit includes a first contact member that comes into contact with a surface of a recording material and a second contact member that comes into contact with the other surface of the recording material, and the first contact member and the second contact member face each other and are capable of nipping the recording material. The first contact member and the second contact member are movable in a direction in which the first contact member and the second contact member nip the recording material. The first contact member and the second contact member are rotatable about an axial line that extends in a direction in which the recording material is conveyed.
