Problems solved by technology

That is, in mass and high-speed printing, it is necessary to supply the toner to the developing device stably and at a high speed. Therefore, as in the above-mentioned document 5, when the toner is concentratedly conveyed to the center of the cartridge main body, the toner is transferred to the center of the cartridge main body. The time required for concentration at the center becomes longer, causing the problem that toner cannot be supplied stably and at high speed to the developing device

Embodiment Construction

[0062] One embodiment of the present invention will be described as follows. In addition, in this embodiment, an example in which the developer replenishing device of the present invention is applied to a printer which is an image forming apparatus will be described.

[0063] FIG. 2 is a diagram showing a schematic configuration of a printer according to this embodiment.

[0064] This printer (A) forms multi-color and monochrome images on predetermined paper (recording paper) based on image data transmitted from the outside. Also, as shown in FIG. 2, the printer (A) is composed of an exposure unit 1, a developer 2, a photosensitive drum 3, a charger 5, a cleaning unit 4, an intermediate transfer belt unit 8, a fixing unit 12, a paper transport path S, a supply The paper tray 10 and the paper output tray 15 are configured.

[0065] In addition, the image data handled by this printer (A) corresponds to color images using the respective colors of black (K), cyan (C), magenta (M...

Abstract

A developer supplying apparatus of the present invention includes a toner bottle, a bottle supporting member that is in the shape of substantially a cylinder, and a shutter mechanism for opening and closing a toner discharging opening formed on the bottle supporting member. The shutter mechanism includes a shutter member which is slidably provided on the bottle supporting member and opens / closes the toner discharging opening, and a protruding portion which is provided on the toner bottle, and when the shutter member is located at such a position that the toner discharging opening is closed, engages with a part of the shutter member so as to stop rotation of the toner bottle. Thus, it is possible to realize the developer supplying apparatus which can stably supply a toner to a development device at high speed.

Description

technical field [0001] The present invention relates to a developer replenishing device for replenishing developer to a developing device. Background technique [0002] As a developer supply device for supplying developer to a developer included in an image forming apparatus such as a printer or a copier, there is a device disclosed in Document 1, for example. [0003] In the developer replenishing device disclosed in the above-mentioned document 1, the toner is conveyed to a predetermined position using a screw provided in the toner container as the developer accommodated in the toner container corresponding to the developer container. [0004] However, when conveying a large amount of toner, the main body of the toner container must be enlarged so that no load is applied to the screw. That is, there is a problem that the proportion of toner that can be accommodated in the toner container decreases. [0005] Therefore, in Documents 2 to 4, technologies are disclosed in wh...
