ABSTRACT:
A recording apparatus in accordance with the invention has an optical system including a laser oscillator for forming an electrostatic latent image of an original on a photosensitive drum, a developing unit for visualizing the image, a tray for stacking transfer sheets, a transfer charger for transferring the image onto a transfer sheet, a fixer for fixing the image on the transfer sheet, a double transfer detector for detecting double transfer of two or more transfer sheets, a ramp detector for detecting a ramp of the transfer sheet, and a central processing unit for inhibiting feeding of the transfer sheet upon sensing of a double transfer or ramp of transfer sheets. When a double transfer or ramp of transfer sheets occurs, the information which may normally be lost may be printed on a transfer sheet in the right order without requiring interruption of the operation of the recording apparatus, so that the throughput of the recording apparatus may not be degraded.
