An electrophotographic plate-making machine including a light source and a movable copy holder forming a scanning exposure system for focusing a light at a focus region. A first electric motor is connected to the copy holder, and a sensitive paper is conveyed by a plurality of conveying rollers. Two of the conveying rollers are arranged at the focus region in series with the remaining conveying rollers. A second electric motor is connected to the conveying rollers and a third electric motor is connected to the focus region rollers. Accordingly, the first, second and third electric drive motors, respectively, can move the copy holder, the conveying rollers and the focus region rollers independently of each other, so that a first scanning exposure can be carried out on one portion of a sensitive paper and a second scanning exposure can be carried out on the remaining portion of the sensitive paper.
