Embodiment Construction

[0026] Next, the image forming apparatus 10 according to the first embodiment of the present invention will be described in detail based on the drawings. In this embodiment, a tandem color printer is exemplified as an example of an image forming apparatus. The image forming apparatus may be, for example, a copier, a facsimile machine, a multifunction machine thereof, or the like. In addition, the image forming apparatus may be a printer, a copier, or the like that forms monochrome (black and white) images.

[0027] figure 1 is a cross-sectional view showing the internal structure of the image forming apparatus 10 . The image forming apparatus 10 includes an apparatus main body 11 having a box-shaped housing structure. Installed in the apparatus main body 11 is a paper feed unit 12 for supplying sheets P, an image forming unit 13 for forming a toner image to be transferred onto the sheet P supplied from the paper feed unit 12 , the toner The intermediate transfer unit 14 to...

Abstract

The invention provides an image forming device. The drive transmission unit included in the image forming apparatus includes a first drive transmission unit and a second drive transmission unit. The first drive transmission unit transmits the rotational driving force of the motor rotating in the first rotational direction to the toner container, thereby conveying the toner contained in the toner container in a predetermined direction, and restricting the The rotational driving force of the motor rotating in the second rotational direction is transmitted to the toner container. The second drive transmission part transmits the rotational driving force of the motor rotating in the second rotation direction to the container cover, thereby changing the state of the container cover from the closed state to the open state, and restricting the movement to the container cover. The rotational driving force of the motor rotating in the first rotational direction is transmitted to the container cover. Accordingly, the opening and closing operation of the container cover for opening the toner container to the outside can be realized at low cost.

Description

technical field [0001] The present invention relates to an image forming apparatus that forms an image on a sheet. Background technique [0002] Conventionally, image forming apparatuses such as printers and copiers using electrophotography include a photosensitive drum carrying an electrostatic latent image, a developing device that supplies toner to the photosensitive drum to make the electrostatic latent image appear as a toner image, and the toner Like a transfer device that transfers from a photosensitive drum to a sheet. [0003] In addition, there is known an image forming apparatus that includes a plurality of developing devices corresponding to color toners of each color, and in this image forming apparatus, a plurality of toner containers that supply replenishing toner to each developing device are arranged. In these techniques, a plurality of openable and closable container covers are provided on the front portion of the device main body. When the container cove...
