An image-forming apparatus includes, in a body having a predetermined house, an image-reading unit and an image-forming unit that is configured to form an image read by the image-reading unit. A discharge portion is configured to discharge a sheet on which the image was formed onto a discharge tray. An intra-apparatus-discharge space is formed in the body between the image-reading unit and the image-forming unit. The housing includes therein a consumption article mounting portion in which a consumption article used by the image-forming unit is mounted. At least a portion of a surface of the housing at a region of the consumption article mounting portion has a light-transmissive property. When the consumption article is consumed and needs to be replenished, the operator can visually check the region of the consumption article mounting portion in the housing from the outside of the body through the transparent portion.

A first protrusion is provided between an operation lever and a lock lever. The operation lever is for moving a pressure roller. The lock lever is provided for a sheet guide member for guiding a sheet that has passed through a fixing unit downstream in the sheet conveyance direction. The lock lever is for locking the sheet guide member at a position where the sheet guide member is engaged with a housing. The first protrusion protrudes from the sheet guide member toward an exterior cover. The first protrusion is provided with a second protrusion on the lock lever side of the first protrusion.

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.

An image forming apparatus may include a photosensitive member, a developing device including a developing roller, pressing members configured to engage with the developing device and springs configured to urge the pressing members. In some examples, each of the pressing members may be configured to contact and move the developing device between various positions based on the urging of the springs. Additionally or alternatively, various ends of a contact surface of the developing roller configured to contact developer may be disposed relative to an axis line of the developing roller and pressing surfaces of the pressing members.

A housing includes a housing main body that has an opening in one surface; a first cover that is openably and closably supported by the housing main body by means of a first rotation portion, that covers at least a portion of the opening, and that is provided with an operation portion that causes the first cover in a closed state to enter an open state, the first rotation portion being provided on a portion of the one surface that is on one side with respect to the opening in one direction; and a second cover that is openably and closably supported by the first cover and of which an operation portion that causes the second cover in a closed state to enter an open state is provided at a position that is separated from the operation portion of the first cover by at least half a distance between the operation portion of the first cover and the first rotation portion in the one direction while being on the first rotation portion side.

An apparatus includes an openable and closable cover, a movable member disposed in the apparatus main body and to be exposed outside when the cover is opened, an openable and closable support member that supports the movable member, and a support shaft that supports the cover and the support member. The movable member and the support member are moved together with the cover as the cover rotates about the support shaft. The support shaft can move between a first position at which the support shaft supports the cover and the support member and a second position at which the support shaft does not support the cover and supports the support member. Moving the support shaft to the second position allows the cover to be detached from the apparatus main body.

An image forming apparatus includes an apparatus main body to which a cartridge is detachably attached. The apparatus main body includes a frame having an opening portion through which the cartridge is attached to the apparatus main body; an opening and closing member supported by the frame rotatably between an open position in which the opening portion is exposed and a closed position in which the opening portion is covered with the opening and closing member and having a stacking surface on which a sheet is to be stacked; a discharging roller discharging the sheet in a discharging direction onto the stacking surface; and a regulating wall which is movably attached to the opening and closing member and extends from the stacking surface toward the discharging roller in a direction intersecting the discharging direction to regulate an upstream edge of the sheet in the discharging direction.

An apparatus includes an apparatus body, an exterior cover configured to pivot around a pivot shaft extending in a first direction, and extend in the first direction and a second direction orthogonal to the first direction, a first engagement portion including a first engagement surface, and a second engagement portion, the second engagement portion including a facing surface facing the first engagement surface. When viewed in a third direction orthogonal to an exterior surface of the exterior cover, the first engagement surface and the facing surface at least partially overlap each other. The facing surface includes a second engagement surface and an inclined surface. When viewed in the third direction, a ridgeline formed by the second engagement surface and the inclined surface extends further away from the pivot shaft in the second direction as the ridgeline extends more downstream in the first direction.

An image forming apparatus includes an apparatus body including a main contact, and a main guide, and a cartridge including a memory contact, a moving unit moving into and out of the apparatus body in a first direction and including a frame to which the cartridge is attached, first and second protrusions protruding in a second direction orthogonal to the first direction from the end surface of the frame, an intermediate contact being in electrical contact with the memory contact, an unit contact being in electrical contact with the main contact, and a line conductor, the first protrusion being supported by the main guide of the apparatus body, the second protrusion being located above the first protrusion. At least part of the line conductor connecting the intermediate contact and the unit contact is located in a recess formed by the first protrusion, the second protrusion, and the end surface.

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.
