Abstract
A copying machine which develops an electrostatic latent image corresponding to an original image into a toner image, transfers the toner image on the copying paper and fuses the toner image later on the copying paper by means of a heating and fusing device, detects types of copying papers to be transferred by the toner image and when the copying paper is large in size, a fixed standstill time is arranged between the scanning and exposing operation of an original and a restoring operation to a home position is made and a fusing operation is prevented without fail when a temperature of the heating and fusing device drops below a fusing temperature.
