Abstract: An image forming apparatus includes an image bearing member, a developer bearing member, a discharge unit, a stacking tray including a stacking surface on which the recording material is stacked, a replenishment port, a cover capable of moving between a closed position where the cover covers the replenishment port and constitutes at least part of the stacking surface and an open position where the cover exposes the replenishment port, and an information display unit for displaying information about a procedure for replenishing the developing container with the developer from the replenishment container.

Abstract: An image forming apparatus includes a first metal plate provided with a through hole; a second metal plate provided opposed to the first plate; a third metal plate provided between the first plate and the second plate; and a fixing member fixing the first plate and the third metal plate to each other. The fixing member has a first surface and a second surface extending in a direction crossing the first surface. The third metal plate extends outward in a direction in which the first plate and the second plate opposes to each other, and the third metal plate is provided with a first projection penetrating the through hole, and wherein the first projection is fixed on the first surface. The first plate is fixed on the second surface of the fixing member.

Abstract: An image forming apparatus according to the present invention includes an optical box, a housing having a discharge opening, a cover provided downstream of the optical box in a discharge direction in which a recording material is discharged through the discharge opening and forming a part of the housing, and a circuit board, wherein the circuit board includes a plurality of electronic components and a wiring board configured to electrically connect the plurality of electronic components, the circuit board is disposed in such a direction that a surface of the wiring board on which the plurality of electronic components is mounted intersects the discharge direction, and the wiring board is provided between the cover and the optical box in the discharge direction, and wherein, when viewed in a vertical direction, the optical box and the plurality of electronic components partially overlap each other.

Abstract: An image forming apparatus includes an attachment portion to which to attach a supply container for supplying a developer, a housing including a discharge portion for discharging a sheet in a discharging direction, a discharge tray including a first stack portion for stacking the sheet thereon, in which the first stack portion is configured to be movable between a closed position and an opened position, a top portion fixed to the housing, and a display portion and an operation portion arranged on the top portion. The top portion includes a first region, a first extension portion, and a second extension portion. As viewed along a vertical direction, the first extension portion and the second extension portion extend from the first region in the discharging direction, and at least a part of the first stack portion is located between the first extension portion and the second extension portion.

Abstract: A positioning apparatus includes an apparatus body, a draw-out portion, and a positioning mechanism configured to position the draw-out portion at an attachment position with respect to the apparatus body, wherein the positioning mechanism includes a first engaging portion provided in one of the apparatus body and the draw-out portion, a first engaged portion provided in another of the apparatus body and the draw-out portion and configured to determine a position of the draw-out portion in an attachment direction by engaging with the first engaging portion, and wherein the first engaged portion includes an inclined surface that is inclined downward toward a downstream side in the attachment direction and causes a force in the attachment direction to act on the draw-out portion on a basis of a weight of the draw-out portion in a state in which the first engaged portion is engaged with the first engaging portion.
