Embodiment Construction

[0051] Preferred embodiments of the present invention will be described in detail below with reference to the drawings.

[0052] First, the image forming apparatus 100 including the toner cartridge 200 according to the first embodiment of the present invention will be described. figure 1is a schematic diagram showing the configuration of the image forming apparatus 100 . The image forming apparatus 100 is a multifunctional peripheral having a copying function, a printing function, and a facsimile function, and forms a full-color image or a monochrome image on a recording medium based on transmitted image information. The image forming apparatus 100 has three printing modes: a copy mode (copy mode), a print mode, and a facsimile mode. According to an operation input from an operation unit not shown in the figure, a personal computer, a mobile terminal device, an information recording medium, or a memory card is used. When receiving a print job from an external device of the de...

Abstract

A toner discharging device, a toner cartridge, and an image forming apparatus in which the occurrence of the locking phenomenon is prevented are provided. A toner discharging device includes a discharge container including a wall portion which defines an inner space and has a reception port and a discharge port, and a discharge member which includes an inner spiral blade moving toner in a direction H1, an outer spiral blade moving toner in a direction H2, and a rotation shaft. At least a part of the wall portion surrounds both the inner spiral blade and the outer spiral blade along an axial line direction of the rotation shaft, and the discharge port is formed on the part of the wall portion.

Description

technical field [0001] The present invention relates to a toner discharge device, a toner cartridge and an image forming device. Background technique [0002] An electrophotographic image forming apparatus performs development with toner contained in a developing device to form an image. In the field of such image forming apparatuses, a toner cartridge for replenishing toner to a developing device is conventionally known. The toner cartridge is configured to replenish the toner stored in the toner cartridge into the developing device when the toner in the developing device is consumed due to image formation. [0003] For example, JP-A-2006-235255 describes a toner cartridge having the following components: a storage container for storing toner; a discharge container extended on the storage container and provided with a discharge port for discharging toner; and a discharge member that conveys the toner in the storage container into the discharge container and discharges it ...
