Abstract

In a printing position adjusting mechanism employed in an image forming apparatus using a continuous form recording medium having perforated tear lines at predetermined intervals, are sensors are provided for detecting a leading edge of the recording medium and outputting a predetermined signal synchronously with the feeding of the recording medium. With the printing position adjusting mechanism, the period of time, between the detection of the leading edge of the continuous sheet and outputting of the predetermined signal, is adjustable. The apparatus starts printing upon receiving the predetermined signal which is outputted after a predetermined time has elapsed after the leading edge of the continuous sheet is detected.
