設けたことを特徴とする複写機用現像装置。 A developing device for a copying machine is composed of two components: toner and carrier, in which developer is mixed in a developer tank, and includes a toner tank that stores toner and replenishes the toner to the developer tank as needed, and a toner tank that stores toner and supplies toner to the developer tank. A toner cartridge that is detachably attached to the tank and replenishes toner to the toner tank at once when attached to the toner tank; an attachment detection means that detects attachment of the toner cartridge; and an attachment detection means for detecting attachment of the toner cartridge. A number counting means for counting the number of copies after being detected by the detection means; and a remaining toner amount detecting means for detecting the presence or absence of a remaining amount of toner in the toner tank based on the number of copies counted by the number counting means. A developing device for a copying machine, characterized in that it is provided with the following.
