Image forming apparatus

An image forming apparatus comprising:

• a casing configured to accommodate an image forming unit forming an image on a sheet;
• a manual feeder tray provided on a side portion of the casing and configured to support the sheet;
• a trailing edge supporting member provided above the manual feeder tray with respect to a vertical direction, the trailing edge supporting member supporting a trailing edge portion of the long sheet of which a leading edge portion is supported by the manual feeder tray;
• and
• a feeding unit configured to feed the sheet, of which the leading edge portion is supported by the manual feeder tray and the trailing edge portion is supported by the trailing edge supporting member, toward the image forming unit in a feeding direction,
• wherein the trailing edge supporting member is configured to rotate about a shaft extending in a sheet width direction that is perpendicular to the feeding direction as a rotational center between a usage position and a retraction position,
• wherein the usage position is a position where the sheet to be used is supported and a center of gravity of the trailing supporting member is more apart from the image forming unit than the rotational center is from the image forming unit with respect to a horizontal direction perpendicular to the vertical direction and the sheet width direction,
• wherein the retraction position is a position where the trailing supporting member is retracted and the center of gravity of the trailing supporting member is at a side closer to the image forming unit than the rotational center is to the image forming unit with respect to the horizontal direction, and
• wherein the trailing edge supporting member includes:
• a supporting portion extending from the rotational shaft to an upstream side in the feeding direction and configured to support the trailing edge portion of the sheet in the state in which the trailing edge supporting member is positioned at the usage position, and
• an inclined portion provided on an end portion side that is farther than the rotational shaft and inclined to the supporting portion so as to approach to the manual feeder tray toward upstream of the feeding direction in the state in which the trailing edge supporting member is positioned at the usage position.
