置。 An endless belt photoreceptor, a belt drive device that transports and drives the photoreceptor through the front surface of a recording sheet, a charging device that uniformly charges the surface of the photoreceptor, and a charging device that charges the surface of the photoreceptor after being charged according to a recording signal. An electrophotographic recording head consisting of an optical writing device that exposes to light to form an electrostatic latent image and a developing device equipped with a developing sleeve that develops the electrostatic latent image on the surface of the photoreceptor is mounted on the carriage. In a serial type printing device in which the recording head is moved parallel to the surface of the recording paper together with a carriage to transfer a developed visible image on the photoreceptor onto the recording paper, a small-diameter printer that receives the back surface of the photoreceptor in a stretched state. A developing gap adjustment roller comprising a roll portion and a large diameter roll portion that presses into contact with the surface of the developing sleeve to maintain a constant gap between the surface of the photoreceptor on the small diameter roll portion and the surface of the developing sleeve. A printing device featuring:
