Abstract

PURPOSE:To make the detection of jam sure by receiving the light emitted from a light emitting element and reflected from the nonimage part of sheet paper with a photodetector. CONSTITUTION:The passage of transfer paper 1 is detected well with a reflection type detecting elememt 14 in the nonimage part 16 outside the image part 15 of transfer paper 1. This is accomplished without any obstacle even in the case of copying both sides of the transfer paper 1. The transfer paper 1 advances thereafter to a fixing part by passing on a guide plate 17, but the transfer paper 1 near a stripping roller 6 and stripping rollers 61, 62 will not flap, thus for the detecting element 14, the position of the transfer paper 1 is stable, hence this is extremely convenient.
