Abstract

PURPOSE:To prevent staining such as photographic fog, blurr, etc. of recording owing to unnecessary toners and improve recording quality by providing a magnet roll for recovering the unnecessary magnetic toner stuck on an electrostatic latent image carrying body. CONSTITUTION:The electrostatic latent image formed on an electrostatic latent image carrying body 1 such as photosensitive drum or the like is developed by the magnetic toner 4 in a toner box 3 by a magnet roll 2. At this time, the unnecessary magnetic toner stuck on the parts other than the electrostatic latent image is recovered by a magnet roll 6 for recovering unnecessary toner. The unnecessary magnetic toner is magnetically attracted to the roll 6 before it arrives at recording paper 5, and is recovered into a recovery box 7.
