Abstract: In a sheet feeding device, a main body includes a feeding unit configured to feed a sheet in a feeding direction to a conveying path. A cover is configured to pivot about a first axis relative to the main body between a closed position in which the cover closes the conveying path and an open position in which the cover exposes the conveying path. A plate is configured to pivot about a second axis which is parallel to the first axis and to contact and move away from the feeding unit. The second axis is closer to the cover than to the feeding unit in the feeding direction. In a state in which the cover is in the closed position, at least a part of the cover is positioned on an upper side of the plate so as to be contactable with the plate.

Abstract: A hinge mechanism, which connects a first member and a second member, comprising: a plurality of bases, a plurality of shafts, which are provided at the plurality of bases one by one, and protrude from the bases, a plurality of shaft receiving units, which are provided in the second member, and include shaft holes into which the shafts are rotatably fitted, respectively, and a regulating stopper, wherein when a force is applied at the regulating stopper, the regulating stopper is bent from a position where the regulating stopper contacts with a regulated unit to a position where the regulating stopper does not contact with the regulated unit.

Abstract: A light source is provided in the casing and emits a light beam for forming an image. A first sensor receives the light beam emitted by the light source and outputs a light reception signal. A cover opens and closes relative to the casing. A shutter prevents the first sensor from receiving the light beam when the cover is at an open position, and allows the first sensor to receive the light beam when the cover is at a closed position. A controller is configured to: execute a lighting process of lighting the light source; execute a first determining process of determining whether the light reception signal is outputted from the first sensor, in response to the lighting process; and determine that the cover is at the open position upon determination in the first determining process that no light reception signal is outputted.

Abstract: An image forming apparatus includes a main body having a first opening; a main cover supported by the main body, having a second opening and rotatable between a first closed position and a first opening position with respect to the first opening; a feeder cover supported by the main cover and rotatable between a second closed position and a second opening position with respect to the second opening; and a link arm jointed to the main body at a first joint, jointed to the main cover at a second joint, the first joint movable relative to the main body, and the link arm rotating the feeder cover from the second opening position toward the second closed position when the main cover rotates from the first closed position with the feeder cover at the second opening position.

Abstract: An image forming apparatus includes: a main body casing; a fixing unit accommodated in the casing and including a heating member and a pressing member; a first wall provided inside the casing at a position above the heating member and the pressing member and extending diagonally downward and forward; an uneven portion provided on the first wall at a position rearward of front end portion of the pressing member to restrain a dew droplet condensed on the first wall from running down along the first wall; a sheet ejection opening formed in the casing such that the recording sheet conveyed out from the fixing unit is ejected outside the casing through the sheet ejection opening; and an exhaust opening formed in the casing at a position rearward of the heating member such that air heated in the fixing unit is discharged outside the casing through the exhaust opening.

Abstract: An image forming apparatus includes an ejection tray including a support portion, a plurality of ejection rollers having a nip portion, and a tray cover having a first surface and a second surface and being configured to move between an extended position where the first surface faces upward and a covering position where the tray cover is supported by the support portion to cover an upper surface of the ejection tray and the second surface faces upward. When the tray cover is in the covering position, an upstream end portion of the second surface of the tray cover in a sheet ejection direction is disposed in a position closer to the nip portion than the upper surface of the ejection tray and lower than the nip portion such that a leading end of the recording sheet ejected from the nip portion passes on or over the second surface.

Abstract: An image forming apparatus includes an image forming unit configured to form an image on a recording medium, wherein a first gas is generated during image formation, and a fixing unit configured to fix the image onto the recording medium by heat, wherein a second gas is generated during image fixing by heat. A body includes a chamber and an opening through which the first gas and the second gas are guided into the chamber to be mixed into a gas mixture. A fan discharges the gas mixture from the chamber.

Abstract: An image forming apparatus is provided. The image forming apparatus includes: a conveying path that includes a first U shape portion; a registration roller; and a inverting path including a second U shape portion joining with an upstream position of the registration roller. The conveying path includes a downward slope portion that runs obliquely down from a topmost position of the first U shape portion toward a nipping position of the registration roller; and wherein the topmost position, a joining position in which the conveying path is connected to the inverting path and the nipping position get lower, in this order, in a vertical direction.
