ABSTRACT:
An apparatus for developing electrostatic latent images with a two-component developer consisting of carrier and toner, comprising (a) a developer container, (b) a magnetic roll provided in the container, comprising a permanent magnet and a non-magnetic sleeve, (c) a hopper mounted on the container for replenishing toner to the container, (d) a roller provided in the container near its wall on the opposite side to the magnetic roll for mixing the developer with the toner replenished from the hopper and stirring them, (e) a device having a detection surface for detecting the concentration of toner in the developer. The detection device is mounted on the wall of the container such that the detection surface is located near the mixing roller to ensure the developer to flow smoothly and stably between the mixing roller and the detection surface.
