た、 ことを特徴とする現像装置。[Claims for Utility Model Registration] A developer consisting of non-magnetic toner and magnetic particles is carried on a developer carrier having a multi-pole magnetic field generating means with alternating north and south poles, and the carried developer forms a latent image. In a developing device that develops a latent image on the surface of a holding body with toner, magnetic poles are sequentially arranged from the most upstream side to the downstream side in the direction of movement of the carried developer facing the developer supply side to the developer carrying body. A developing device characterized in that the magnetic force is gradually increased from the most upstream side to the downstream side.
