Image forming apparatus

An image forming apparatus comprising:

• a sheet feeding unit that houses recording sheets of a predetermined size and feeds the recording sheets one by one;
• a manual sheet feeding unit disposed at a position where recording sheets can be placed on the manual sheet feeding unit from an outside of the image forming apparatus directly, the manual sheet feeding unit feeding the placed recording sheets one by one;
• wherein the manual sheet feeding unit comprises a tray on which the recording sheets are stacked, the tray protruding from a main body of the image forming apparatus toward an outside of the main body;
• an image forming unit that forms an image on a recording sheet supplied from the sheet feeding unit or the manual sheet feeding unit;
• a first sheet conveyance path that conveys the recording sheet from the sheet feeding unit to the image forming unit;
• a second sheet conveyance path that conveys the recording sheet from the manual sheet feeding unit to the image forming unit;
• and
• an air-blowing unit that blows air to an edge of the recording sheets stacked on the manual sheet feeding unit, wherein:
• the first sheet conveyance path and the second sheet conveyance path are merged together before the first sheet conveyance path and the second sheet conveyance path reach the image forming unit, and
• the air-blowing unit is disposed in a vicinity of the first sheet conveyance path before merged and a conveyance roller provided in the first sheet conveyance path.
