An image forming apparatus includes an image forming unit, a main body including the image forming unit and having an opening open in a horizontal direction, a sheet supply tray including a contact portion, a retaining mechanism disposed at the main body, a feed roller disposed at the main body, a pivotable member disposed at the main body and including a contact portion, and a clutch mechanism. The pivotable member is configured to, when the sheet supply tray is attached to the main body, pivot from a first position to a second position by the contact portion of the pivotable member receiving a force having the vertical direction from the contact portion of the sheet supply tray. The clutch mechanism is configured to allow or cut-off transmission of a driving force to the feed roller in response to the sheet supply tray relative to the main body. |

1. An image forming apparatus comprising:
an image forming unit configured to form an image on a sheet; a main body including the image forming unit and having an opening open in a horizontal direction; a sheet supply tray detachably attached to the main body through the opening and configured to receive a stack of sheets to be supplied to the image forming unit, the sheet supply tray including a contact portion; a feed roller disposed at the main body and configured to feed a sheet received at the sheet supply tray toward the image forming unit; a retaining mechanism disposed at the main body and downstream of the feed roller in a direction in which the sheet supply tray is attached to the main body, the retaining mechanism being configured to retain the sheet supply tray attached to the main body; a pivotable member disposed at the main body and including a contact portion, the pivotable member being configured to, when the sheet supply tray is attached to the main body, pivot from a first position to a second position different from the first position in a vertical direction by the contact portion of the pivotable member receiving a force having the vertical direction from the contact portion of the sheet supply tray; and a clutch mechanism configured to, when the contact portion of the pivotable member is in contact with the contact portion of the sheet supply tray, transmit a driving force to the feed roller, the clutch mechanism being configured to, when the contact portion of the pivotable member is separated from the contacted portion of the sheet supply tray, cut off transmission of the driving force to the feed roller, wherein the contact portion of the pivotable member is formed as a curved surface inclined with respect to an insertion direction in which the sheet supply tray is inserted into the main body. |
