Improvements are provided in and relating to an electrostatic copying apparatus including a housing, a support for supporting an original to be copied, the support being mounted on the housing and having a transparent plate for supporting the original thereon and a holding member for covering the original on the transparent plate, a system for forming a copied image disposed within the housing and having an optical system for projecting the image of the original on the transparent plate, and a system for transferring a copying paper synchronously with the scanning of the original which is effected by the relative movement of the original holder and the optical system. The improvements include an improvement in the control of the cutting of the copying paper where the copying paper-transferring system includes a system for supplying a roll of copying paper; an improvement in a device for starting the supply of copying paper synchronously with the scanning of the image of the original; an improvement in a device for supplying the roll of copying paper in the copying paper-transferring system; and an improvement in a device for supplying a copying paper in sheet form in the copying paper-transferring system.
