Abstract

PURPOSE:To prevent a fault in transfer and to speed up carrier by providing a proper means for detecting a transfer sheet on a carrier path for a transfer sheet and controlling the rotating speed of a fixing roller which specifies the carrier speed of the transfer sheet according to the signal thereof. CONSTITUTION:In an image forming device in which the transfer of an image is completed by a photosensitive drum 31 and the transfer sheet is carried by the fixing rollers 45 so as to execute thermal fixing, a switch S1 which is turned on if the transfer sheet contacts is provided on the carrier path for the transfer sheet. And while the S1 is turned on, the rotating speed of the fixing roller is equalized to that of the photosensitive body and if the switch S1 is turned off, the rotating speed of the fixing roller is accelerated. A switch S2 is provided just before the transfer sheet enters the photosensitive drum and detects that the tailing edge of the transfer sheet passes a transferring area. And if the switch S2 is turned off even the 1st switch S1 is turned on, the rotating speed of the fixing roller is accelerated after a certain time by a timer, so that the acceleration of carrier can be attained and the fault in transfer can be prevented.
