摘要： In the electrophotographic apparatus for printing one or more copies of a document, a photoconductive drum rotates at a constant velocity while being charged; a document feeding device advances a document through a light exposure portion at a constant speed and, an optical device projects an image of the exposed document onto the drum to form an electrostatic charge latent image thereon. A latent image is developed to form a toner image after which the toner image is transferred onto a record paper and the toner image is fixed on the record paper to form a final copy. Clock pulses in synchronism with the rotation of the photosensitive drum are produced, whereby master and slave timing pulse generators receive the clock pulses to produce timing pulses. Then a control device receives the timing pulses and produces control signals necessary to control the operation of the apparatus. The duplicating operation for forming a single copy is divided into two portions, each of which is respectively assigned to the master and slave timing pulse generators. During duplication and while under the control of the slave timing pulse generator, a new duplication for a next document can be initiated under the control of the master timing pulse generator.
