Electrostatic reproducing apparatus |
摘要 |
An electrostatic reproducing apparatus characterized in that a sensor unit consisting integrally of at least one light emitting element and one light receiving element is disposed close to the surface of a photosensitive member at a position downstream of the position where the printed sheet of recording paper separates from the photosensitive member. One of the light emitting elements is a visible-light emitting diode for detecting jamming of the sheet of recording paper and the other light emitting element is an infrared-light emitting diode for detecting the toner concentration.
