Abstract:
1. A developing apparatus, comprising: a developer carrying member; an image carrying member disposed adjacent to the developer carrying member; and an air-flow conveying unit that conveys the toner with an air pressure to fly the toner, wherein the air-flow conveying unit includes a pipe, one end of an extending direction of the pipe provided with an injection nozzle that injects toner toward the developer carrying member, and a toner collecting unit that collects toner from the developer carrying member provided at another one of the ends, wherein the developing apparatus performs image visualization processing by electrostatically adhering toner carried on the developer carrying member onto an electrostatic latent image formed on the image carrying member, and wherein the toner supplied to the developer carrying member is directly injected onto the developer carrying member after flying inside an electric field generated in the air-flow conveying unit immediately before reaching the developer carrying member, the electric field having one of a homopolarity and a reverse polarity to the electrostatic latent image.
