ABSTRACT:
A developing apparatus using a dry developer in the form of a toner. The apparatus includes a housing having an opening which is located to face a photoconductive element. A vent is formed through the housing to release a pressure being developed in the housing, while a filter closes the vent to filter out a toner cloud. A smooth air guide plate which is more than 5 millimeters wide is provided in an edge portion of the opening downstream of a developing position with respect to an intended direction of a rotation of the photoconductive element. The air guide plate is spaced apart from the photoconductive element by a distance less than 2 millimeters and serves to increase the velocity of air flowing into the housing through the opening and, thereby, prevents toner particles from being released to the outside of the apparatus.
