Abstract

A developer scattering prevention unit used with an electrophotographic image forming device includes an air inlet/outlet pipe installed adjacent to an intermediate area between an image carrier and a developer and having a first air inlet/outlet port opened toward the intermediate area, and at least one vacuum source installed on at least one of the image carrier and the developer carrier to communicate with the air inlet/outlet pipe to control air to flow from the intermediate area through the first air inlet/outlet port. A developing device having this developer scattering prevention function becomes simplified in structure.
