IMAGE FORMATION APPARATUS |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide an image formation apparatus which can reduce heat generation of a substrate of a photoreceptor drum due to induction heating. <P>SOLUTION: An image formation apparatus includes: a photoreceptor drum with a photosensitive layer formed on a cylindrical substrate; latent image formation means for forming a latent image on the photoreceptor drum; development means that has a developer carrier comprising a developing sleeve for carrying two-component developer composed of toner and carrier and magnetic field generating means rotatably included in the developing sleeve and having plural magnetic poles and that develops a latent image on the photoreceptor drum, and electrical resistivity of the substrate is higher than 2.65×10<SP POS="POST">-6</SP>[Ω cm]. <P>COPYRIGHT: (C)2012,JPO&INPIT |
