<p>PURPOSE:To provide an image forming device, in the image forming device composed of a photosensitive drum in which an exposure means is inserted and a developing sleeve containing a magnet composing body. CONSTITUTION:As developer, one containing at least high-resistance or insulated toner is employed. An exposure position is set near the position where the surface potential of a photosensitive body 1 produced by the sliding of developer in a slide area shows the maximum value. As a concrete device, the developer composed of at least carrier whose surface is conductive-processed and the high-resistance or insulated toner is used, and the exposure means 3 is composed in such a manner that it can swing to change the exposure position at least within a part of the width of the developer slide area 10 formed between the photosensitive body 1 and the toner carrier 20.</p> |
