The present invention relates to a method of detecting a rear edge of a recording medium using a passage detection lever for swinging in association with a passage of the rear edge of the recording medium, and a detection sensor for detecting swinging movement of the passage detection lever. The present invention comprises the steps of detecting a conveying quantity of the recording medium at a prescribed interval recording a past data of the conveying quantity and determining a position of the rear edge of the recording medium based on the recorded past data with consideration of a physical returning time starting from a point of time when the rear edge of the recording medium passes the passage detection lever and causes the swinging of the passage detection lever to a point of time when the detection sensor detects the swinging movement.
