Abstract

PURPOSE:To assuredly select an unrecorded sheet for a double sided recording device, by applying a fluorescent material on the 1st surface as soon as the recording is carried out to then store it and setting a fluorescent detecting means at a transport path for recording on the 2nd surface. CONSTITUTION:A recording sheet is sent out from a paper feed stand 1A(1B) and has the transcription of a picture formed on a photosensitive drum 4 on the 1st surface via a roller 3 to be guided (a) to a switch guide 8 after the transport 6 and fixing 7 and then to be stored temporarily to a relaying tray 9. In the course of the fixing, a fluorescent material is applied on the 1st surface. The transfer sheets stacked densely are squeezed by a fixing roller 7 to be separated from each other. Then the unrecorded sheets are detected by fluorescent detectors 16a and 16b. The stacked sheets which are separated on the way of transfer are treated as the jamming by sensors 13a-13i. After this, the picture is transcribed on the 2nd surface from the drum 4 via a transport path 11 and the roller 3 and then guided (b) to the guide 8 after the transport 6 and fixing 7 to be stored in a sorter 15.
