An image forming apparatus includes an attaching portion including an operation member configured to be movable together with a container shutter, a toner storage portion configured to store toner received from a receiving port, an actuator configured to regulate a movement of the operation member, and a control unit configured to control the actuator. The operation member is configured to open and close the container shutter from an outside in a state in which the toner container is attached to the attaching portion. In a case where a predetermined condition is met, the control unit controls the actuator to release a regulation of the movement of the operation member.

Image forming apparatus for use with detachable toner container

An image forming apparatus forming an image on a sheet conveyed in a sheet conveyance direction includes a frame including a first side plate and a second side plate disposed in parallel in a width direction orthogonal to the sheet conveyance direction, an intake unit disposed on an outer side of the frame in the width direction and configured to draw air into an interior of the frame, an exhaust unit disposed between the first side plate and the second side plate and configured to discharge air outside of the frame, and a cooling object unit disposed on a path of the air which is drawn into the interior of the frame by the intake unit and moves toward the exhaust unit.

Image forming apparatus having widthwisely extending exhaust fan

An image forming apparatus includes a photosensitive drum, a development device, a fixing device, an apparatus main body, and a fan including a rotating shaft that extends in a longitudinal direction of the photosensitive drum and a blade around the rotating shaft. The development device develops a toner image on the photosensitive drum. The fixing device fixes the toner image from the photosensitive drum to a recording material. The apparatus main body is provided with a discharge port from which the toner-fixed recording material is discharged. A length of the fan rotating shaft in the longitudinal direction is longer than a diameter of a rotational trajectory of the blade. The fan is provided on a downstream side of the fixing device in a discharge direction in which the recording material is discharged from the discharge port and overlaps a part of the development device when viewed in a vertical direction.

Image forming apparatus

An image forming apparatus includes an apparatus body, an image forming unit, an opening and closing cover, a fixed cover that constitutes a part of an exterior of the apparatus body with the opening and closing cover, and is configured to form a boundary portion with an upper edge of the opening and closing cover in a vertical direction, a positioning portion including a first engagement portion provided in the opening and closing cover, and a second engagement portion provided in the fixed cover, a first conveyance guide provided on the opening and closing cover, and a second conveyance guide provided on the fixed cover. The first engagement portion and the second engagement portion are configured to engage with each other to perform positioning of the opening and closing cover and the fixed cover in the vertical direction and positioning of the first conveyance guide and the second conveyance guide.

An image forming apparatus configured to form an image on a sheet includes a main body, an opening and closing part, a link part, and an urging member. The link part is connected to the main body and the opening and closing part. When the opening and closing part moves between open and closed positions, the link part moves perpendicular to a direction along a rotating shaft of the link part to contact and be received by the main body. The opening and closing part can move in a state in which the link part and the main body contact each other. When the opening and closing part is in the closed position, the link part and the main body are separated from each other, and the opening and closing part is urged toward the main body by the link part urged by the urging member.
