Abstract
A developing device in an electrostatic copying apparatus. The developing device includes a developer container, a developer applicator for holding on its surface a pair of a developer present in the developer container and applying toner particles to a latent electrostatic image to be developed, and a toner particle dispenser for dispensing toner particles therein to the developer container. The toner particle dispenser is controlled such that it performs a toner particle dispensing action in response to the performance of a copying process by the electrostatic copying apparatus. The developing device is provided with a device for inhibiting the dispensing of toner particles which makes the toner particle dispenser unable to start a toner particle dispensing action when a sufficient amount of the developer is present in the developer container.
