Problems solved by technology

[0009] However, this transmission unit has a disadvantage when electrostatically adsorbing recording paper: a relatively high amount of moisture present in the recording paper significantly reduces the surface resistance on the adsorption surface of the charging belt and reduces the charge on the belt, resulting in a decrease in adsorption capacity
But the arrangement of the heaters complicates the device and according to the scheme an additional power source is required

Abstract

Disclosed is a recording ink for ink-jet recording comprising a colorant, water, a humectant, a surfactant, and a wetting agent, wherein the recoding ink is applied to ink-jet recording apparatuses capable of recording on a second recording side of a recording medium following recording on a first recording side of the recording medium, and the infiltrating period of the recording ink into the first recording side of the recording medium is 5 seconds or less. Also, an ink cartridge, an ink-jet recording apparatus, an ink-jet recording process, and a recorded matter are disclosed that utilize the recording ink respectively.

Description

technical field [0001] The present invention relates to a recording ink suitable for inkjet recording, and an ink cartridge, an inkjet recording apparatus, an inkjet recording method, and a recorded matter respectively using the recording ink. Background technique [0002] Recently, recording devices such as inkjet printers and plotters employing pigmented inks to improve printing performance on plain paper have been commercially produced. These recording devices are partially recordable on both sides. [0003] However, a device capable of double-sided recording results in lower productivity compared with single-sided recording while providing the advantage of saving paper, because ink with lower paper penetration is used in order to use black ink to obtain high image density, and the second side is in the Printing rates are generally low as the first side is printed after a sufficient drying period before being printed to avoid contamination during printing. [0004] An i...
