リツジ式現像装置。[Claims for Utility Model Registration] 1. A cartridge type developing device that can be easily attached to and detached from the main body of a copying machine, including a toner concentration detector, a reference value memory, and an output value of the toner concentration detector obtained at a predetermined time. The toner replenishment control circuit includes a reference value setting means for storing a reference value in the reference value memory and a toner replenishment control circuit for outputting a toner replenishment signal based on a comparison between the output value of the toner concentration detector and the reference value stored in the reference value memory. A cartridge type developing device characterized by the following. 2. The reference value setting means is a means for reading the output value of the toner concentration detector when a predetermined time has elapsed after the cartridge-type developing device is attached to the copying machine main body and first energizing, and storing this as a reference value in the reference value memory. A cartridge type developing device according to claim 1 of the utility model registration claim.
