Problems solved by technology

[0005] However, in such a structure using a linearly sliding shutter, in order to ensure the stability of the operation of the shutter, it is necessary to arrange biasing members such as coil springs on both sides of the feed port, and a plurality of biasing members are required.
Therefore, an increase in the number of parts and an increase in manufacturing cost

[0026] First, use figure 1 , the overall configuration of the electrophotographic printer 1 will be described. figure 1 It is a schematic diagram showing the outline of the printer according to the first embodiment of the present invention. Below, with figure 1 The left side of the paper in is taken as the front side (front side) of the printer 1.

[0027] The printer 1 includes a box-shaped printer body 2 . A paper feed cassette 3 for storing paper (not shown) is housed in the lower part of the printer body 2 , and a paper output tray 4 is provided on the upper surface of the printer body 2 . On the upper surface of the printer main body 2 , an upper cover 5 is openably and closably attached in front of the paper discharge tray 4 , and a toner container 6 serving as a toner container is housed below the upper cover 5 .

[0028] On the upper part of the printer main body 2 , an exposure unit 7 is disposed below the paper discharge tray 4 . The exposure unit 7 is consti...

Abstract

The present disclosure relates to an image forming apparatus and a development device. An image forming apparatus includes a toner container and a development device. The toner container includes a container main body being provided with a discharge port configured to discharge a toner. The development device includes a development device main body being provided with a replenishment port configured to receive a toner discharged from the discharge port and a shutter configured to open / close the replenishment port. The shutter opens / closes the replenishment port by turning along the outside face of the development device main body. According to the invention, the operation operation stability of the shutter can be secured, while the number of components is reduced.

Description

technical field [0001] The present invention relates to an image forming apparatus and a developer provided in the image forming apparatus. Background technique [0002] An electrophotographic image forming apparatus performs a development process by supplying toner (developer) from a developer to an electrostatic latent image formed on a surface of a photosensitive drum or the like. In addition, the toner used for this developing process is supplied to the developing device from a toner container detachably attached to the developing device. Therefore, the developer is provided with a supply port for receiving toner from the toner container. The feed port is usually covered by an openable and closable baffle. [0003] Figure 16 A structural example of the above-mentioned baffle is shown. The baffle 121 has an upwardly inclined inclined surface 122 and has a substantially triangular shape in side view. The shutter 121 is linearly slidable between a position for closing ...
