装置。[Scope of Claim for Utility Model Registration] In an image forming apparatus capable of copying continuous paper such as computer format paper as a document, a sensor for detecting that a document is set;
A device for automatically conveying the document, and a registration section for supplying transfer paper so as to be in contact with the drum surface in response to the rotation of the photoreceptor drum, and the document is continuous like the computer format paper described above. The registration unit is driven a required time earlier than the position of the original image on the photoreceptor drum surface when it is detected that the original is a document, thereby preventing copy loss of an image at the edge of a unit page of the original. A control device for copying computer paper.
