Sheet feeding apparatus, document reading apparatus and method for feeding sheet

A document reading apparatus, comprising:

• image reading member that reads a document to be fed;
• a driving roller that is rotated by a predetermined driving source and sending said document to a position at which said image reading member is arranged, said driving roller being arranged before said image reading member;
• a driven roller that rotates in response to movement of said driving roller, said driven roller having contact with a roller surface of said driving roller and being arranged opposite said driving roller;
• a pressing member that presses a roller surface of said driven roller toward said roller surface of said driving roller at a predetermined pressure;
• and
• driven roller holding member that includes an opening being elongated in a tangential direction at a contact point between said driven roller and said driving roller or between said driven roller and a sheet, on a circle forming said roller surface of said driven roller.
