Abstract

PURPOSE: To eliminate the need for adjustment at the changing of magnifications, at the assembling and adjusting or even after the long-term operation and perform paper feed controlling of high accuracy stable for a long period of time by performing paper feed controlling with the pattern corresponding to the leading end or the like of the original having been formed simultaneously with the formed images of a photoreceptor.
CONSTITUTION: A pattern 21a or 21b is beforehand provided to the leading end of the original as shown in the A part and is projected together with the original onto a pnotosensitive drum 8. The pattern 21a' or 21b' developed together with the orignal is reflected by a lamp 22 at the B point and the reflected light is detected with an optical detector 23. At this time, if the distance l2 from resistor rollers 42, 43 up to transfer part 32 and the distance l1 from the detecting part up to the transfer part 32 are made equal, the signal of the foregoing element 23 is used as the signal source of high accuracy driving or controlling the registers 42, 43 directly.
