Abstract
A developing apparatus performs image visualization processing by electrostatically adhering toner carried on a developer carrying member onto an electrostatic latent image formed on an image carrying member. In the developing apparatus, the toner to be supplied to the developer carrying member is directly injected onto the developer carrying members after flying inside an electric field generated immediately before reaching the developer carrying member. The electric field has one of a homopolarity and a reverse polarity to the electrostatic latent image.
