Problems solved by technology

Therefore, when printing on the reverse side of the paper, if the uneven (wrinkled) or curled paper is directly fed, there will be a difference in height on the recording surface of the paper, resulting in image degradation.

[0020] In the first embodiment, an inkjet image forming apparatus having four color inkjet heads will be described.

[0021] figure 1 It is a schematic configuration diagram showing an example of an inkjet image forming apparatus according to this embodiment.

[0022] The paper cassette 100 and the paper cassette 101 are used to store paper p of different sizes. The paper feed roller 102 or the paper feed roller 103 is used to take out the paper p corresponding to the selected paper size from the paper cassette 100 or the paper cassette 101 and convey it to the pair of conveying rollers 104 , 105 and the pair of registration rollers 106 . Also, the paper p is not special paper but plain paper.

[0023] Tension is applied to the transport belt 107 by a driving roller 108 and two driven rollers 109 . A plurality of small-diameter through-holes are provided at predetermined intervals on the surface of the conveyor belt 107 . The conveyor belt 107 is an endless belt manufactur...

Abstract

According to one embodiment, an inkjet image forming apparatus includes an inkjet head which ejects an aqueous ink, a recording medium reversing mechanism for reversing a recording medium, and a controller. The controller performs control such that if a both-side recording mode is designated, the location information of an overlapping region of images to be recorded on the front surface and the rear surface is detected, based on the detected recording image location information on the front surface and the rear surface, the density of the images to be recorded at the location on the front surface and the rear surface is determined, and if the image density on one surface is higher than the image density on the other surface, the image density at the location on the one surface is reduced, and controls the inkjet head based on the control.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from US Provisional Application No. 61 / 316,406, filed March 23, 2010, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to an inkjet image forming apparatus and an inkjet image forming method that eject aqueous ink from an inkjet head to form an image on a recording medium. Background technique [0004] An on-demand inkjet image forming apparatus employs a nonimpact method in which ink droplets are ejected from nozzles according to a control signal corresponding to a recording signal, and adhered to a recording medium. Inkjet image forming devices have been rapidly popularized in recent years due to their low noise, high-speed recording of high-precision images, suitability for miniaturization and cost reduction, and various advantages such as easy use of multi-color inks for recordi...
