Abstract

PURPOSE:To eliminate effects in humidity change and detect and control toner contents by detecting the bias current changing with toner quantity in a developer with a counter electrode disposed in the flow of the developer being carried by a carrying means and having finished developing and comparing said current with a reference value.
