ABSTRACT:
An image forming apparatus includes a sheet sensor (7) and a leading end position sensor (9). The sheet sensor (7) detects the passage of a trailing end of a printing sheet (10) along a feeding path of the printing sheet (10) fed by a first feeding roller (2) from a sheet storing portion (1). The leading end position sensor (9) detects a protruding amount of the subsequent printing sheet (102) when the preceding printing sheet (101) is fed by the first feeding roller (2). The feeding of the subsequent printing sheet (102) is started when an adjusting time has elapsed after the sheet sensor (7) detects the passage of the preceding printing sheet (101). The adjusting time is determined according to the protruding amount of the subsequent printing sheet (102) detected by the leading end position sensor (9).
