Abstract
In an image forming device provided with a copy mode of forming an image on the rear surface of a one-surface-copied recording paper and another copy mode of forming am image on both surfaces of the recording paper, the image forming device is provided with a function of selecting the recording paper which is capable of obtaining the desired copy only by selecting and executing the mode of copying without paying attention to the type of the recording paper accommodated in the paper feeding apparatus (whether it is both-surfaces-blank or one-surface-copied). The image forming device further has an image-existence/absence detector for detecting whether the image has been already copied on one surface of the recording paper accommodated in the paper feeding apparatus, and a controller for selecting the paper feeding tray accommodating the recording paper of the size and type fitted to the both-surfaces-copying mode in accordance with the detection signal received from the image existence/absence detector.
