検知ユニット。(1) A sensor member is provided close to the photoreceptor drum on the downstream side of a separating section that separates the transfer paper after the toner image has been transferred from the rotating photoreceptor drum, and detects the presence or absence of the transfer paper on the photoreceptor drum using a sensor member. In the separation error detection unit that detects transfer paper separation errors, a photosensitive member is installed at a position where a gap narrower than the gap between the sensor member and the photosensitive drum circumferential surface is formed between the sensor member and the photosensitive drum circumferential surface. A transfer paper separation error detection unit characterized in that a guide member is provided for guiding the photosensitive drum so as not to contact the sensor when the body drum is attached or detached.
