Abstract:
An image forming apparatus comprising:a rotary means for printing on a paper sheet while rotating; a pressing means for pressing said paper sheet onto said rotary means; a first paper-transporting mechanism including a pair of rollers which are pressed against each other and move away from each other for each rotation of said rotary means, said pair of rollers repetitively being pressed against each other at a first specified timing for transporting said paper sheet towards said rotary means and separating from each other to stop the transportation of said paper sheet at a specified second timing; a second paper-transporting mechanism for repetitively transporting said paper sheet towards said first paper-transporting mechanism and stopping the transportation of said paper sheet at a specified third timing; and a control device for controlling said second paper-transporting mechanism such that said second paper-transporting mechanism transports said paper sheet towards said rotary means for a specified time at a faster speed, after a front edge of said paper sheet being transported by said first paper-transporting mechanism has reached said rotary means and the transportation of said paper sheet by said rotary means has started and when said first paper-transporting mechanism separates said pair of rollers from each other and has stopped the transportation of said paper sheet, said faster speed being faster than a slower speed with which said rotary means transports said paper sheet.
