Abstract
The present invention relates to a developing device which is arranged in an image forming device such as an electronic photo printer and an electrostatic recording-type printer and which develops developer on an electrostatic latent carrier transferring an electrostatic latent image and to an electrostatic recording device including the developing device. The object is to provide a device with high reliability which can decrease developer dispersion and the frequency of maintenance. The developing device consists of a developing roller for conveying a two-component developer by creating a magnetic brush to an electrostatic latent image carrier on which a latent image is formed and for moving in a direction opposite to the moving direction of the electrostatic latent carrier in a developing area to an electrostatic latent image carrier; a developer regulating plate for regulating the amount of the two-component developer to the developing roller; and a dispersion blocking plate protruding toward the developing area from the developer regulating plate.
