Document feeding, image reading, and image forming apparatus including slidable document supporting tray that pivots up from a second position and moves obliquely downward

An image reading apparatus comprising:

• a document supporting tray including a first supporting tray configured to support a document, and a second supporting tray configured to support the document together with the first supporting tray and provided so as to be movable between a first position at which the second supporting tray is located above the first supporting portion-tray and a second position at which the second supporting tray supports the document together with the first supporting tray;
• a document feeding roller configured to feed a document supported by the document supporting tray in a feeding direction;
• and
• an image reading sensor configured to read an image on a document fed by the document feeding roller,
• wherein when the second supporting tray moves from the first position to the second position, the second supporting tray is configured to slide from the first position to an upstream side in the feeding direction, pivot to be more inclined with respect to a horizontal direction than when it is at the first position, and then move obliquely downward.

An image forming apparatus comprising:

• a document supporting tray including a first supporting tray configured to support a document, and a second supporting tray configured to support the document together with the first supporting tray and provided so as to be movable between a first position at which the second supporting tray located above the first supporting portion-tray and a second position at which the second supporting tray supports the document together with the first supporting tray;
• a document feeding roller configured to feed a document supported by the document supporting tray in a feeding direction;
• an image reading sensor configured to read an image on a document fed by the document feeding portion roller;
• and
• an image former configured to form an image on a sheet based on the image on the document read by the image reading sensor,
• wherein when the second supporting tray moves from the first position to the second position, the second supporting tray is configured to slide from the first position to an upstream side in the feeding direction, pivot to be more inclined with respect to a horizontal direction than when it is at the first position, and then move obliquely downward.
