摘要:
A toner conveying means disposed in a housing includes an upstream-side toner conveying means and a downstream-side toner conveying means. A toner amount detector means is disposed to detect whether the amount of toner in the downstream portion of the housing is greater than a predetermined amount or not, and the upstream-side toner conveying means is not operated when the amount of toner is greater than the predetermined amount in the downstream portion of the housing. A toner replenishment signal is produced when the amount of toner does not become greater than the predetermined amount in the downstream portion of the housing despite the downstream-side toner conveying means is operated for more than a predetermined period of time.

An electrostatic latent image-developing device (2) comprises a toner cartridge (16) provided with a container having a toner discharge opening, a toner contained in said container and a sealing tape (128a,128b) for sealing said toner discharge opening (108a,108b), and a toner cartridge-holding means (14) having a toner-receiving opening (34) and allowing detachably to mount said toner cartridge (16). The toner cartridge (16) is equipped with a shutter member (130) that is disposed on one edge side of the toner discharge opening and is so constituted as to move to the other edge side across said toner discharge opening to cover said toner discharge opening. The toner cartridge-holding means (14) is equipped with a shutter-moving means (72) which moves the front edge of said shutter member from one edge side to the other edge side of said toner discharge opening.
摘要:
It is a major object of the present invention to break down and level a heap-up of toner built in the hopper (3) through dropping from the cartridge when feeding toner into the hopper (3) and to prevent toner from leakage from the cartridge due to erroneous operation with a remarkably simple and cheap construction. Namely, the leveling member (29) moves a plurality of number of times in line with engaging and disengaging operation of the cartridge for the hopper (3) and opening and closing operation of the cartridge in the same direction of the shutter, thereby causing a heap-up of toner built in the hopper housing of the hopper to be effectively broken down and leveled. Furthermore, only when the shutter is in its closed status for the cartridge, the cartridge can be removed from the opening of the hopper (3).

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).

A sorter (3) incorporating a stapler (25) is an apparatus for sorting and stapling sheets discharged from an image forming apparatus (5). This sorter (3) includes a plurality of vertically movable bins (23) for storing the supplied sheets, a bin drive unit (24) for conveying the bins (23), a stapler (25) for stapling the sheets stored in the bins (23), a pair of lateral guides (261, 262), and a lateral guide drive unit for moving the lateral guides (261, 262). The lateral guides (261, 262) are movable in the width direction of the sheets in the bins (23) and abut on both sides of stacks of the sheets to arrange them into widthwise adjustment, and then to move them into the stapling position of the stapler (25).
