An image forming apparatus includes a paper tray, an elevating plate, a cam, and a shutter. The paper tray is configured to hold sheets. The elevating plate on the paper tray is arranged to ascend and descend between a descended position and an ascended position higher than the descended position. The cam is movable between a first position and a second position. The shutter includes a shielding portion. The shielding portion is located at a shielding position when the cam moves to the first position. The shielding position is a position that overlaps with a region in a height direction occupied by the cam at the second position. The shielding portion retracts from the shielding position when the cam has moved from the first position to the second position.

An image forming system includes an image forming apparatus having an apparatus main body, a sheet feeding cassette, a manual bypass tray, an opening/closing detection part and a sheet feeding source setting part. The apparatus main body has an input part to which a printing instruction is input. The manual bypass tray is displaced into an open posture and into a close posture. The sheet feeding source setting part sets the sheet feeding cassette or the manual bypass tray as a sheet feeding source. When the opening/closing detection part detects that the manual bypass tray is displaced from the close posture to the open posture and the printing instruction is input to the input part, regardless of the sheet feeding source input to the input part, the sheet feeding source setting part sets the manual bypass tray as the sheet feeding source.

A retracting device includes a housing that is disposed in or on an accommodating unit to be pulled out from an apparatus including a protrusion and that has a groove extending from a first position to a second position and having an opening formed at the first position, the first position corresponding to a position of the protrusion when the accommodating unit moving in a direction in which the accommodating unit is accommodated into the apparatus reaches a predetermined position and the second position corresponding to a position of the protrusion when the accommodating unit is accommodated in the apparatus, and a movable unit that is disposed in the housing and that moves, when the accommodating unit reaches the predetermined position and the protrusion enters the opening, while holding the protrusion to cause the protrusion to move along the groove and with respect to the housing toward the second position.

In an image forming apparatus to which a finisher is connected, a power source control unit shifts the image forming apparatus to a power saving state. The image forming apparatus is inhibited from being shifted to the power saving state when it is detected that a sheet for which a binding process is to be performed is set in the finisher. The image forming apparatus may be permitted to be shifted to the power saving state when it is not detected that the sheet is set in the finisher.

According to one embodiment, an image processing apparatus includes an apparatus main body, a first rotating body, a second rotating body, and a connection member. The first rotating body is configured to be openable and closeable and provided in the apparatus main body. The second rotating body is provided in the first rotating body. The second rotating body is configured to be openable and closable from the first rotating body in the same direction as that of the first rotating body. The connection member is linear. The connection member is configured to connect the apparatus main body and the second rotating body to each other and to restrict a rotation angle of the second rotating body.

An image forming apparatus includes an image forming unit that forms an image on a recording medium and an image forming apparatus body in which the image forming unit is provided, and on which a first manual feeding tray and a second manual feeding tray having a configuration different from the first manual feeding tray are selectively mountable at a same mounting position.

The image forming apparatus includes a side panel and a manual feed tray that is rotatable and installed on the side panel. The side panel includes an opening portion through which a sheet placed on the manual feed tray passes when the sheet is fed into the image forming apparatus. The manual feed tray includes an end cursor that is movable, and a guide portion that guides movement of the end cursor in a direction perpendicular to a rotational center of the manual feed tray. The opening portion is sized to accommodate the end cursor. When the opening/closing angle of the manual feed tray with respect to a horizontal direction exceeds a predetermined angle, the end cursor moves along the guide portion by gravity to a position where the end cursor can be accommodated in the opening portion.

An image forming apparatus includes a paper tray, an elevating plate, a cam, and a shutter. The paper tray is configured to hold sheets. The elevating plate on the paper tray is arranged to ascend and descend between a descended position and an ascended position higher than the descended position. The cam is movable between a first position and a second position. The shutter includes a shielding portion. The shielding portion is located at a shielding position when the cam moves to the first position. The shielding position is a position that overlaps with a region in a height direction occupied by the cam at the second position. The shielding portion retracts from the shielding position when the cam has moved from the first position to the second position.
