Abstract: PURPOSE:To execute a joint erasion by forming a joint erasing pattern by using data for showing necessary joint erasing length and paper data, and also, turning on or turning off a luminous body for erasing a shadow image at a rotational position of a photosensitive body determined by a joint erasing pattern. CONSTITUTION:By a signal 111 for showing a size of a copying paper by receiving a signal 101 for showing to operate a joint erasion, form data for forming a joint erasing pattern is selected, and by using data 102 for showing necessary joint erasing length and the form data, a joint erasing pattern is formed. Subsequently, by comparing a signal for showing a rotational position of a photosensitive body, and the joint erasing pattern, whether each rotational position of the photosensitive body is a position exposed by a luminous body 25 or not is discriminated, and the light emitting means 25 for exposing the photosensitive body at the rotational position of the photosensitive body determined by the joint erasing pattern is turned on or turned off.
