Abstract

An ink jet image forming apparatus, which is improved in a structure of an ink supply device so as to minimize an influence due to a pressure loss generated in an ink flow passage, is provided. The ink jet image forming apparatus includes a print head to eject an ink to a printing medium, an ink tank to store the ink, an ink circulation passage through which the ink circulates between the ink tank and the print head, a pressure controller which has an ink storage unit communicating with the ink circulation passage and an air storage unit communicating with external air, a valve mounted in the ink circulation passage between the ink tank and the pressure controller, a pump mounted in the ink circulation passage and pumps the ink, and a control unit to control operations of the valve and the pump.

Description

technical field

[0001] The present invention relates to an inkjet image forming device, and more particularly to an inkjet image forming device in which the structure of an ink supply device is improved so that ink can be stably ejected from a printing head. Background technique

[0002] An inkjet imaging device is a device that forms an image by ejecting ink onto a printing medium. Inkjet imaging devices generally include an ink supply for supplying ink stored in an ink reservoir to ink channels within the printhead. Ink supplied to the printhead is ejected onto a print medium through the printhead to print an image. At this time, if the ink stored in the ink tank contains gas components dissolved therein, or if air bubbles are generated in the ink when the ink passes through the ink supply device, the ink cannot be ejected stably, which causes image quality problems. deterioration.

[0003] In order to solve this problem, Korean Patent No. 708195 relates to an ink circu...
