Abstract

PURPOSE:To improve developing efficiency and to obtain the developed image of high quality by connecting a permanent magnet roll to a micro-angle oscillator. CONSTITUTION:A permanent magnet roll 3a is connected to a micro-angle oscillator like a vibrator, and oscillates by micro-angles theta around a shaft 4. Thereby, the developing magnetic pole N magnetized on the roll 3a is oscillated by the angles theta, and the contact width of the magnetic brush formed from a magnetic developer 7 is spread in the developing part for the electrostatic latent images formed on a photosensitive drum 1. As a result, the developing efficiency of the electrostatic latent images is improved.
