Abstract
A developing unit for visualizing an electrostatic latent image formed on a photoreceptor drum with a toner, includes: a hopper for storing a developer; a developing roller for supplying the toner to a photoreceptor drum on which an electrostatic latent image is formed; and an agitating and conveying portion. In the developing unit, the agitating and conveying portion includes first and second agitating and conveying belts, each having toner agitating blades for agitating and conveying the toner. The first and second agitating and conveying belts are rotatably arranged in the hopper with their rotational axes set approximately vertically so as to rotate the toner agitating blades approximately horizontally.
