Image forming apparatus and sheet feeding method

An image forming apparatus comprising:

• a drive controller that controls the drive of feeding rollers disposed on the upstream side in the feeding direction relative to an intermediate feeding roller that feeds a sheet to a regist roller that performs skew correction for the sheet;
• a sheet size determination section that determines the sheet size in the feeding direction of a sheet to be subjected to the skew correction performed by the regist roller;
• and
• a timing determination section that determines the timing at which the regist roller starts feeding the skew corrected sheet after the skew correction, wherein
• in the case where the sheet size determination section determines that a sheet to be subjected to the skew correction performed by the regist roller is larger than a predetermined size, when the timing determination section determines that a predetermined timing for the regist roller to start feeding the skew corrected sheet has come, the drive controller drives the feeding rollers by a predetermined time from the predetermined timing.

A sheet feeding method comprising:

• a drive control step that controls the drive of feeding rollers disposed on the upstream side in the feeding direction relative to an intermediate feeding roller that feeds a sheet to a regist roller that performs skew correction for the sheet;
• and
• a timing determination step that determines the timing at which the regist roller starts feeding the skew corrected sheet after the skew correction, wherein
• when the timing determination step determines that a predetermined timing for the regist roller to start feeding the skew corrected sheet has come, the drive control step drives the feeding rollers by a predetermined time from the predetermined timing.
