たことを特徴とする現像装置。 A developing device that adsorbs toner made of component magnetic developer onto the surface of a magnet roll to form a toner layer, brings it into contact with an electrostatic latent image, causes the toner to adsorb to the surface of the electrostatic latent image, and creates a visible image. A conveyance magnet roll that conveys the toner and a development magnet roll that attracts the toner to the electrostatic latent image surface are arranged, and the toner layer thickness is adjusted in proximity to the conveyance magnet roll and the development magnet roll, respectively. A regulating means is provided to regulate the thickness of the toner layer of the developing magnet roll regulated by the layer thickness regulating means to be greater than the thickness of the toner layer of the conveying magnet roll, and A developing device characterized in that the circumferential speed of the conveying magnet roll is set faster than the speed of the conveying magnet roll.
