ABSTRACT:
In a dry process developing apparatus, a seal member closes a gap between a photoconductive element and the upper end of a housing which has a developing roller, a toner supply roller and the like thereinside. A blade for regulating the thickness of a toner layer on the developing roller is spaced at its base end portion from the wall of the housing to set up a toner recirculation path. An oscillator plate extends generally downwardly to neighbor the toner supply roller at the free end thereof. The free end of the vibrator is caused into oscillation by a drive unit. The oscillator and drive unit cooperate to guide a toner dropped by a toner replenish device, which replenishes the toner to the housing, toward the toner supply roller.
