写機の現像装置。 A developing roller is disposed facing the rotating photoreceptor, and a developing roller is provided on both ends of the developing roller and presses against the outer peripheral surface of the photoreceptor to maintain a constant gap between the photoreceptor and the developing roller. In a developing device of a copying machine, which is equipped with a tracking roller and supplies developer from a developing roller toward the photoreceptor holding an electrostatic latent image, the tracking roller is pressed against the rotation center of the photoreceptor. A developing device for a copying machine, characterized in that:
