Electrostatic latent image-developing device and toner cartridge used therefor.

摘要

An electrostatic latent image-developing device is equipped with a toner cartridge-holding means (14) and a toner cartridge (16) fitted thereto. The toner cartridge (16) includes a container (144) with toner discharge openings (150a, 150b), a toner (T) contained in the container (144), and a sealing means (192a, 192b) for sealing the toner discharge opening. The sealing means (192a, 192b) is constituted by a tape member that is provided to move across the toner discharge opening (150a, 150b), and a toner passage (198a, 198b) opening is formed in the tape member (192a, 192b). The toner discharge opening (150a, 150b) is opened when the tape member (192a, 192b) is so moved that the toner passage opening (198a, 198b) is positioned at the toner discharge opening (150a, 150b). The toner cartridge-holding means (14) includes a hoist frame (58) that moves up and down, and the toner cartridge (16) is held in this hoist frame (58).
