ABSTRACT:
An image forming apparatus for forming an image on a sheet supplied thereto, wherein a time period required for a first sheet passing a predetermined position in a sheet conveying path is measured, and the measured time period is compared with a previously set time period. The sheet supply operation is controlled so that, when the measured time period is shorter than the set time period, operations of supplying second and subsequent sheets are started with a time interval equal to the difference between the time periods, and, when the measured time period is equal to or longer than the set time period, operations of supplying second and subsequent sheets are started immediately.
