Image forming apparatus

An image forming apparatus comprising:

• a tray;
• a roller unit including:
• a feed roller disposed above a downstream end portion of the tray in a sheet conveying direction in which a sheet is conveyed, the feed roller being configured to rotate in contact with an upper surface of a sheet supported on the tray and feed the sheet from the tray;
• a separation roller disposed downstream of the feed roller in the sheet conveying direction and configured to rotate in contact with the upper surface of the sheet fed by the feed roller, separate the sheet singly and feed the sheet to a conveying path;
• and
• a roller holder pivotable about a rotation axis of the separation roller, the roller holder holding the feed roller rotatably about an axis of the feed roller and pivotably vertically;
• an image forming unit disposed downstream of the tray in the sheet conveying direction and configured to form an image on the sheet conveyed along the conveying path;
• and
• a pressing mechanism configured to press the roller unit toward the sheet supported on the tray, the pressing mechanism including:
• an arm member pivotable about the rotation axis of the separation roller and disposed in contact with the roller holder, the arm member being configured to press the roller holder such that the roller holder pivots downward;
• and
• a weight portion provided to the arm member and applying, to the arm member, a load in a direction in which the feed roller is raised from the upper surface of the sheet supported on the tray.
