Imaging unit and image formation apparatus provided with the same

Abstract

The invention relates to an imaging unit and an image formation apparatus provided with the same. In the imaging unit (3) comprising a toner bottle (19) provided with a drive shaft (31) and a print unit (10) provided with a drive shaft (41), the toner bottle (19) is connected with the print unit (10) by an elastic member (48). One-body, double-body type imaging units (3) can prevent the print unit (10) from generating the color fringe. The imaging unit (3) for connecting the toner bottle (19) with the print unit (10) by the elastic member (48) enables the member to be mounted on the image formation apparatus main body (2) generalized and the member to be mounted can be mounted, no matter whether the imaging unit (3) is the one-body type or double-body type. In addition, the cost due to generalization is prevented from increasing.

Description

technical field [0001] The present invention relates to an image forming unit composed of a toner bottle and a printing unit connected to each other to form a toner path, and an image forming apparatus including the image forming unit. Background technique [0002] Conventionally, there is known an image forming apparatus equipped with an image forming unit including a toner bottle and a printing unit. Each of these toner bottles and the printing unit is provided with a drive shaft, and a drive force is obtained from the side of the main body of the image forming apparatus to which it is mounted. [0003] The toner bottle of the imaging unit used in the image forming apparatus and the printing unit are connected in the following ways: in order to reduce the cost of introducing consumables each time, parts such as baffles are reduced, and the toner bottle and the printing unit are integrated (integrated type). ); In order to suppress the cost of the image forming apparatus d...

AI Technical Summary

Problems solved by technology

Since the generation of color fringing is caused by the difference in the structure of the one-piece imaging unit and the two-body type, the problem cannot be eliminated without changing the structures of the two

Therefore, if the above-mentioned problems are eliminated without changing the structure of the image forming unit, the installed parts of the main body of the image forming apparatus cannot be universalized.

[0007] As a solution to the above-mentioned problems, the positioning of the toner bottle relative to the main body of the image forming apparatus is loosened, and it is considered that the driving force to the toner bottle is transmitted to the toner bottle by a flexible drive transmission mechanism from the main body of the image forming apparatus, but the parts The number increases, the cost rises

[0008] In addition, it is also considered to fix the printing unit firmly to the main body to solve the pressing (protrusion つ Zhang り) caused by vibration and positioning, but the cost increases due to the need to increase the rigidity of the main body of the image forming apparatus and to add fixing members.
