Problems solved by technology

[0004] However, in recent years, the miniaturization of image forming apparatuses has been considerably developed, and the space that has not been effectively used as described above has also become less.
In addition, it is desirable to replace the toner storage container as little as possible, so it is difficult to reduce the size of the toner storage container itself.

Embodiment Construction

[0031] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] figure 1 It is a schematic diagram of a color copier which is an example of a color image forming apparatus according to the present invention. Such as figure 1 As shown, the center of the color copier is a copier body 100 , a table-shaped paper feeding unit 200 is arranged below it, a scanner 300 is arranged above the copier body 100 , and an automatic document feeding device 400 is arranged above the scanner 300 .

[0033] An intermediate transfer belt 13 is provided in the copier body 100 as an image carrier, and is composed of a flexible endless belt wound around several rollers 14 , 15 , 16 . One of the rollers 14, 15, 16 is driven to rotate by a driving device not shown, and then the intermediate transfer belt 13 is driven to move clockwise as indicated by the arrow, and the other rollers are driven to rotate. Black, cyan, magenta, and ye...

Abstract

The present invention relates to an image forming apparatus provided with a developing device and a toner container, the toner container (80Y, 80C, 80M, 80Bk) having a rectangular cross-sectional shape and a substantially rectangular parallelepiped, at least one toner container (80Bk) ) is different from other toner containers in that the length L1 of the short side of the cross section of the large toner container (80Bk) is substantially equal to the length L2 of the long side of the cross section of the small toner container. Provided is an image forming apparatus capable of efficiently arranging a plurality of toner storage containers, effectively utilizing space, and preventing an increase in the size of the apparatus body.

Description

technical field [0001] The present invention relates to image forming devices such as printers, copiers, and facsimile machines. Background technique [0002] Conventionally, an electrophotographic image forming apparatus is provided with a developing device that performs visible image processing on an electrostatic latent image formed on an image carrier. Toner storage units such as toner bottles, toner cartridges, and toner tanks supply toner with a screw or the like. In addition, in recent years, among image forming apparatuses, image forming apparatuses for obtaining color images tend to increase. In such color image forming apparatuses, four developing devices and four colors (yellow, magenta, cyan, Black) toner storage section. Furthermore, the image forming apparatus is also required to be miniaturized without reducing the toner storage capacity of the toner storage unit. Disposing the toner storage unit near each developing device not only hinders the miniaturizati...
