現像剤残量の検知装置。 A developing device that stores toner for development and forms a toner image on a photoreceptor, a detector that detects the amount of charge carried by the toner transferred to the photoreceptor, and a cumulative value storage that holds the cumulative value of the amount of charge. a limit value holding means for holding a predetermined limit value obtained from the relationship between the remaining amount of toner and the cumulative value of the charge amount, and comparing the outputs of the previous cumulative value holding means and the previous limit value holding means. A device for detecting a remaining amount of developer in a copying machine, comprising a comparing means and a display means for displaying that the remaining amount of toner has reached a limit value based on the comparison result of the comparing means.
