摘要： A predetermined sheet retaining plane C for absorbing a record sheet is provided in the circumferential surface of a sheet carrier, and a low-reflectivity area which is to be partially covered with the record sheet is provided at a leading portion of the sheet retaining plane C. Reflection photosensors for detecting the reflectivity of the sheet carrier including the low-reflectivity area are disposed around the sheet carrier. Whether a record sheet is held in the sheet retaining plane C is judged on the basis of detection signals of the photosensors.
