することを特徴とする現像装置。[Claims for Utility Model Registration] A magnetic brush is formed by a developing sleeve equipped with a magnetic material with respect to the electrostatic latent image formed on the photoconductor, and the developing process is performed by the rotational movement of the developing sleeve. In a developing device for visualizing an electro-latent image, a magnetic body is provided at a predetermined position on both ends of the developing sleeve in the longitudinal direction facing the roller surface, and the magnetic body forms a magnetic brush with respect to the developing sleeve. A developing device characterized by:
