A toner case includes a case main body, a housing frame, a communicating port, a conveying rib, and a conveying screw. The case main body is capable of containing a waste toner. The housing frame is configured to communicate with an inside of the case main body and to rotatably support the case main body. The communicating port is opened on a circumferential face of the housing frame and connected with an image forming part. The conveying rib rotates integrally with the case main body in a first direction so as to convey the waste toner along a direction of introducing the waste toner into the case main body. The conveying screw rotates integrally with the case main body in the first direction so as to convey the waste toner introduced into the housing frame via the communicating port toward the inside of the case main body.

This application is based on and claims the benefit of priority from Japanese patent application No. 2015-240483 filed on Dec. 9, 2015, which is incorporated by reference in its entirety.
The present disclosure relates to a toner case which contains a toner (developer), and an image forming apparatus which includes the toner case.
An electrographic image forming apparatus includes a developing device which develops a toner image on a surface of a photosensitive drum (image carrier) by using a toner supplied from a toner case. Further, the image forming apparatus includes a cleaning device which removes the toner remained on the surface of the photosensitive drum. The toner removed by the cleaning device is collected as a waste toner in a waste toner case.
FIG. 1 is a sectional view schematically showing an internal structure of a color printer according to a first embodiment of the present disclosure.
FIG. 2 is a perspective view showing a part of a toner supplying device, in the color printer according to the first embodiment of the present disclosure.
FIG. 3 is a sectional view schematically showing the toner supplying device, in the color printer according to the first embodiment of the present disclosure.
A preferred embodiment of the present disclosure will be described below with reference to the accompanying drawings. Incidentally, in the following description, a near side in FIGS. 1, 3 and 10 is a front side, and a direction shown in each drawing serves as a reference.
An entire configuration of a color printer 1 as an image forming apparatus according to a first embodiment of the present disclosure will be described with reference to FIG. 1. FIG. 1 is a sectional view schematically showing an internal structure of the color printer 1.
The color printer 1 includes an apparatus main body 2, a sheet feeding cassette 3 and a sheet ejection tray 4. The sheet feeding cassette 3 is attachable to and detachable from a lower part of the apparatus main body 2 of a roughly cuboid shape. In the sheet feeding cassette 3, (a bundle of) sheets S are contained. The sheet ejection tray 4 is arranged at an upper part of the apparatus main body 2. Incidentally, the sheets S are not limited to pieces of paper and may be resin films or OHP sheets.
