An image forming apparatus includes a body housing with an inner space, and an image forming unit. The body housing includes a front cover, a top cover, and an interlocking mechanism. The interlocking mechanism lifts a front end of the top cover by a predetermined distance in association with an operation of opening the front cover from a state that the top cover and the front cover are closed. The interlocking mechanism holds a closed state of the top cover for a period until the front cover is closed from a state that the top cover is closed and the front cover is opened.

An imaging device having a fuser and print engine architecture that enables complete interchangeability between fuser types with a common print engine. The imaging device has a frame configured to separately receive a first fuser assembly of a first fuser type and a second fuser assembly of a second fuser type different from the first fuser type. The first fuser assembly includes a first fuser frame having a first datum tab. The second fuser assembly includes a second fuser frame having a second datum tab. The frame of the imaging device has a datum aperture that is sized to receive the first datum tab that when inserted into the datum aperture, causes the first fuser assembly to be positioned at a first operative position, and the second datum tab that when inserted into the datum aperture, causes the second fuser assembly to be positioned at a second operative position.

An image forming apparatus includes an apparatus body including an image bearing member configured to bear a toner image, a transfer unit including a transfer portion configured to transfer the toner image born on the image bearing member onto a sheet, the transfer unit being pivotably supported with respect to the apparatus body, an opening/closing unit disposed at a position farther from the apparatus body than the transfer unit is, and openably and closably supported with respect to the apparatus body, and a positioning portion pivotably supported with respect to the apparatus body and configured to position the transfer unit with respect to the apparatus body. The positioning portion is entirely disposed further on an outer side in the apparatus body than a pivot center of the transfer unit in a horizontal direction.

An image forming apparatus includes a main body; a door configured to be connected to the main body by a hinge; a feeding part configured to include a feeding roller for feeding a paper and a pressure roller pressurized to the feeding roller by elastic force of an elastic member to form a nip together with the feeding roller; and a movable member configured to reduce the elastic force applied to the pressure roller so that the pressure roller is moved in a nip releasing direction according to an opening operation of the door.

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.

An image forming apparatus includes a restriction member that is rotatable between a first position, in which opening of a locking cover is restrictable in engagement with the locking cover, and a second position in which engagement with the locking cover is disengaged, a coil spring that urges the restriction member to the first position, a solenoid that is driven according to electric conduction to move the restriction member to the second position, a link member that transmits driving force generated in the solenoid to the restriction member, and a restraint part that restrains movement of the link member in a direction crossing a driving direction.

An image formation apparatus according to an embodiment may include: an exposure unit configured, when a cover member is opened from a closed position to an open position, to move from a first position to a second position with respect to the cover member; and a lock mechanism. When the cover member is in the open position, the exposure unit is movable between the second position and a third position in which the angle of the exposure unit relative to the cover member is different from that in the second position. The lock mechanism locks a position of the exposure unit when the exposure unit is in the third position. The lock mechanism releases the lock of the position of the exposure unit, when the cover member is moved from the open position to the closed position in the state where the exposure unit is in the third position.

An image forming apparatus includes a casing, an image forming unit, an outer cover, a first inner cover arranged to face an inner side of the outer cover in a closed state, the first inner cover being made of resin, a second inner cover arranged to face the inner side of the outer cover in the closed state, the second inner cover being made of resin, a first fan, and a second fan. The first inner cover includes a first duct configured to guide air taken in from an exterior of the image forming apparatus by rotation of the first fan to the image forming unit. The second inner cover includes a second duct configured to guide air taken in from the exterior of the image forming apparatus by rotation of the second fan to the image forming unit.

An image forming apparatus includes a conductive frame, a first support portion that is provided on the frame and is conductive to the frame, a door configured to be opened such that an inside of the image forming apparatus is accessed, the door including a metal portion, a second support portion that is conductive to the metal portion, is pivotably connected to the first support portion about a pivot shaft, and is configured to support the door, and a contact portion that is conductive to the metal portion and comes into contact with and is conductive to the first support portion in a case where the door is in a closed state, and a holding mechanism configured to hold the door in the closed state.

A panel apparatus includes: a body having an interior space open to an outside of the panel apparatus via an opening; one of a protrusion and a recess in the interior space; an input panel having a first surface, a second surface behind the first surface, and an input part provided in the first surface; a support part provided in the body to support the input panel such that the input panel pivots relative to the body; an arm protruding from the second surface and configured to guide the input panel such that the input panel pivots relative to the body by being inserted into the interior space through the opening; and the other of the protrusion and the recess which is provided in a part of the arm inserted into the interior space. Pivoting of the input panel is regulated by engagement of the protrusion and the recess.
