Abstract

PURPOSE: To prevent development unevenness and ground soiling, by moving the carrier stretched by carrier guide means while keeping contact with the sleeve surface, and feeding toner into the wedge space formed by the two parts.
CONSTITUTION: A carrier guide means 11 forms electrostatic latent image, and causes a recording paper 15 moved in the direction of arrow by conveying means to contact with the circumference of a sleeve 12. In this case, consisting of a first roller 16 as the first guide member, and a second roller 17 as the second guide member, the rollers 16, 17 are made of conductive materials, and are provided rotatably. Between a recording paper 15a and sleeve 12, wedge section spaces A, B are formed in the upstream side and downstream side, across the boundary of contact part 18 thereof, and a doctor plate 19 as the toner holding means is provided in the lower part of the space A, with one side edge 10a placed closely at gap G to the sleeve 12. In this constitution, development unevenness and ground soiling may be prevented.
