Abstract
A speed control device used in an image forming apparatus which includes a detector for checking whether the backing of an image receiving sheet is made of ordinary paper or OHP film, and is capable of controlling the rotating speeds of the motors depending upon the type of the image receiving sheet, i.e., an ordinary paper type or an OHP film type, thereby ensuring that the thermoplastic resin is molten to achieve optimum fluidity irrespective of the type of image receiving sheet.
