Abstract
An image developing apparatus capable of developing high quality images without a fog and a toner density fluctuation over an extended period of time while reducing a driving torque in an image developing operation is disclosed. The image developing apparatus may includes a toner conveyer device having its surface coated with a ceramic for conveying non-magnetic single component toner to the image bearer in order to develop the latent image, and a lamination controller device for controlling a thickness of non-magnetic single component toner lamina to be formed on the toner conveyer device.
