The figure illustrates a small copier concept providing a good balance between manufacture and operating cost on the one hand and copy rate on the other hand. In small copiers the cost of power, both in terms of the cost of the power supply as well as the power necessary to run the machine during its useful life are important considerations. It is desired to have the power requirements in such a machine be as low as possible. The figure illustrates a small copier concept employing a two-speed, two-cycle arrangement and a radiant fuser wherein the power level required for the fuser is maintained at a reasonable level. In the apparatus illustrated the photoreceptor belt 10 is initially charged uniformly by corotron 20, exposed through exposure rneans 12 to a document transported past the exposure slit on moving platen 14. In the first cycle of operation, the electrostatic latent image thereby formed on the photoreceptor belt 10 is developed at combined developing/cleaning station 16 while copy paper is fed by paper feeder 18 in registration with the lead edge of the image on the photoreceptor belt to be transferred by corotron 20 to the copy paper. Thereafter, the copy paper with the toner image thereon in image configuration is passed through radiant fuser 24 to fix the toner particles onto the copy paper. Subsequently, the copy paper with the toner image thereon is transported out of the machine. While the toner image is being fused to the copy paper, the belt is
