Abstract

PURPOSE:To make possible the reproduction of low contrast images and the reproduction of gradation characteristic by combining a toner-conveying roller of higher surface energy and a developing roller of lower surface energy. CONSTITUTION:The device is provided with a roller 2 which lets the one component type high resistance toner from a toner hopper 3 be deposited on its surface and conveys the same, an electrode 5 which charges the toner on the roller 2 to + polarity, and a developing roller 8 which moves in the same direction at the same speed as the roller 2 and whose surface 10 has the surface energy lower than that of the roller 2. The toner having been charged is transferred from the roller 2 to the roller 8, whereby the electrostatic latent images are developed.
