no. 1 approach

[0054] Fig. 1 is a sectional view viewed from the front side, schematically showing the configuration of a first embodiment of the toner cartridge of the present invention.

[0055] As shown in FIG. 1 , a toner cartridge 1A has a toner storage container 10A and a toner discharge unit 20 provided in the toner storage container 10A.

[0056] This toner storage container 10A has a container main body 11 as a container component and a lid member 12 as another container component, and has a generally rounded rectangular parallelepiped appearance.

[0057] The container main body 11 is a container with a rectangular upper opening and includes a trunk forming wall 11A extending longitudinally and having a flat left side wall 11a, a flat right The side wall 11b, the bottom wall 11c formed in a rounded manner continuously with the left side wall 11a and the right side wall 11b, and the protruding wall 11d provided to protrude outward at the upper end of the right side wall 11b, the rea...

no. 2 approach

[0071] The toner container (not shown) of the second embodiment has the same structure as that of the first embodiment, but is different in that, with the structure (1) as described above, the container main body and the cover member constituting the toner storage container Has overall electrical conductivity. Specifically, in the second embodiment, the entire container main body and the entire lid member are formed of ABS resin in which carbon black having an average primary particle diameter of about 80 nm is uniformly dispersed at about 15% by weight.

[0072] Also in the case of this toner cartridge, approximately 10 -3 A / cm 2 The alternating current flows therein to reduce the adhesive force of the electro-peelable adhesive with respect to the container main body and the cover member, and the toner storage container can be detached. In this case, the voltage may be applied for 30 seconds at 30 volts, for example.

no. 3 approach

[0074] Fig. 4 is a sectional view viewed from the front side, schematically showing the configuration of a third embodiment of the toner cartridge of the present invention. In FIG. 4, the same elements as those in the first embodiment shown in FIGS. 1 to 3 are denoted by the same reference numerals.

[0075] In the toner cartridge 1B according to the third embodiment, with the configuration (2) as described above, the container main body 11 and the cover member 12 constituting the toner storage container 10B have conductivity in the vicinity of the bonding area. In particular, in the toner cartridge 1B according to the third embodiment, the container main body 11 and the cover member 12 are covered with metal plates 15, 16 in the vicinity of their bonding area, and the other configurations are the same as those of the first embodiment. .

[0076] The following will mainly describe the points in which the third embodiment differs from the first embodiment.

[0077] In this to...

Abstract

A toner cartridge comprising: a toner storage container with a toner discharge port, including a plurality of container component members, and a toner discharging unit for discharging toner stored in the toner storage container outside through the toner discharge port, wherein the plurality of container component members are mutually joined by an electrically-peeling adhesive whose adhesion force is reduced by electrification.

Description

technical field [0001] The invention relates to a toner box, an imaging device provided with the toner box, and a method for recycling the toner box. Background technique [0002] An image forming apparatus that forms images by using an electrophotographic system is often used in copiers, printers, facsimiles, etc. and is widely used because of its ability to form high-quality images with simple operations and its easy maintenance. An image forming apparatus with a general electrophotographic system mainly includes a photoconductor drum for forming an electrostatic latent image, a developing device for developing the electrostatic latent image, a transfer device for transferring a toner image onto paper, and a A fuser for fixing toner images onto paper. [0003] Consumed toner and paper can be replenished by the user when used up, however since the toner is made of very light and fine particles, when the toner is supplied to the imaging device, the toner may scatter into th...
