Problems solved by technology

[0003] In such a liquid ejection system image forming apparatus, there is a problem that, since the ink liquid containing the colored material is formed into droplets to form an image, the dots formed by the liquid droplets are scattered in a feathery shape, When ink droplets of different colors are adjacent to each other and land on the recording medium, multiple colors are mixed with each other, resulting in problems such as color mixing with unclear color boundaries. In addition, there is a problem that it takes time to dry the droplets on the paper after printing.

Abstract

The invention relates to a foam coating device, comprising a foam supplying unit(20B) for changing a process liquid(34) accommodated in a processing liquid box(20A) into foam to be supplied to a coating roller(20C); a recovering unit(70) for recovering the surplus foam(32A) except the foam(32) coated on a paper(12) by the coating roller(20C); a second storage chamber(72) for storing the recovered surplus foam(32A); a heating device(74) for heating the second storage chamber(72) and recuperating the stored surplus foam(32A) into the processing liquid; a cleaning liquid supplying channel(75) for enabling a cleaning liquid to be supplied and stored in the second storage chamber(72); and a restoring flow path(76) for enabling the recuperated processing liquid and cleaning liquid to flow in the processing liquid box(20A).

Description

technical field [0001] The present invention relates to a foam application device and an image forming device. Background technique [0002] As image forming apparatuses such as printers, facsimile machines, copiers, plotters, and their multifunction machines, for example, image forming apparatuses of a liquid ejection recording method using a recording head ejecting ink droplets are known. Such an image forming apparatus of an inkjet recording method ejects ink droplets from a recording head onto a moving recording medium to form an image. [0003] In such a liquid ejection system image forming apparatus, there is a problem that, since the ink liquid containing the colored material is formed into droplets to form an image, the dots formed by the liquid droplets are scattered in a feathery shape, When ink droplets of different colors are adjacent to each other and land on the recording medium, multiple colors are mixed with each other, resulting in problems such as color mi...
