Problems solved by technology

Therefore, although the toner can be reliably scraped by the scraping member when there is little toner in the toner container, when a large amount of toner remains in the toner container, the scraping member will The load of the toner is large, and there is a problem of deterioration of the toner
In addition, as a reaction to the load on the toner, a large load is also applied to the scraping member, and there is a possibility that the scraping member may be damaged.

Abstract

A rotary-type toner supply device (20) includes a toner container (211) and a scraping member (212). The toner container (211) has a peripheral wall section (211a) which is shaped so as to surround a side face of an imaginary column (K1) along the side face and has a toner discharge port (211aa) formed therein, and contains toner in space surrounded by the peripheral wall (211a). The scraping member (212) is contained in the space so as to freely rotate around a central axis (S) of the imaginary column (K1), and has first and second curved parts, each of the first and second curved parts (212a, 212b) extending along a portion of a half cycle or more of a spiral on the side face of the imaginary column (K1).

Description

technical field [0001] The present invention relates to a toner replenishing device and an image forming device. Background technique [0002] An image forming apparatus mounted in a printer, a copier, or the like forms an image using toner stored in a developing device included in the image forming apparatus. In the field of such image forming apparatuses, a toner replenishing device for replenishing toner to a developing device is conventionally known. When the toner in the developing device is consumed and becomes low, the toner replenishing device replenishes the toner in the toner container included in the toner replenishing device to a toner hopper connected to the developing device. , the toner hopper sequentially replenishes the replenished toner to the developing device. [0003] In recent years, a rotary toner replenishing device that replenishes toner by rotationally driving a toner container by a rotary drive source included in an image forming apparatus has be...
