<p>A mechanical sheet path sensor used in an electrophotographic image forming apparatus for transcribing image onto a cut sheet by using a toner image formed on a rotating photosensitive drum, for sensing a cut sheet passing therethrough and is placed between a peel-off unit for peeling off the cut sheet after image transcription is performed by an image transcribing unit and a fixing unit for fixing the toner image transcribed on the cut sheet so that a distance from the peel-off unit to the sheet path sensor is shorter than a distance measured along the circumference of the drum from the image transcribing unit to a cleaning unit for cleaning the toner left on the drum after the image transcription. The sensor touches only a side zone where the toner image is forbidden to be transcribed, for avoiding the toner image, not fixed, on the cut sheet from damaging.</p> |
