Test pattern data corresponds to a test pattern including a first pattern area and a second pattern area. In the first pattern area, patterns extending in a second direction are provided in a stepwise manner in correspondence with respective recording elements such that a gap in the second direction is provided between a back end of one of the patterns or each pattern and a front end of the pattern adjacent thereto. In the second pattern area, pattern columns extending in the second direction are provided in a stepwise manner in correspondence with a set of a predetermined number of consecutively provided recording elements such that a gap in the second direction is provided between a back end of one of the pattern columns or each pattern column and a front end of the pattern column adjacent thereto, the predetermined number being two or more consecutively provided recording elements.

An ink-jet line printer () is constituted by multiple ink-jet heads (-to-). Actuators (-to-) are arranged so as to be moved between a home position and a print position, and backup mechanisms (-to-) are arranged at home positions. In this ink-jet line printer, the ink-jet heads can be protected and recovered by backup mechanisms, thus making high-speed continuous printing possible. Even though the backup mechanisms are incorporated, a compact apparatus can still be achieved.

An image forming apparatus that includes an image forming component, a flash fixing component and a control component is provided. The image forming component forms toner images using at least two toners respectively having different colors and transfers the formed toner images onto a recording medium. The flash fixing component emits a flash light onto the recording medium onto which the toner images have been transferred by the image forming component and fixes the toner images. The control component that controls the image forming component to form the toner images so that, among the toner images, a second color toner is adhered to a surface of a toner layer formed by a first toner color at a region at which the toner layer formed by the first toner color is formed, the absorbance of the second color toner being lower than that of the first color toner.

Image forming apparatus, image forming control method, and recording medium recording image forming control program

The fixing apparatus used in an image forming apparatus and fixing an image on a recording medium, the fixing apparatus is provided with: a flash lamp that emits flash light for fixing the image; and a reflection member that has a reflection surface reflecting the flash light emitted from the flash lamp to the recording medium. A shape of the reflection surface is configured so as to be deformable.

A new flash fixing device configured to fix a toner image by a flash light is presented. This flash fixing device includes a plurality of flash lamps arranged parallel to each other, and a reflection board including a plurality of side part reflection surfaces each facing from a side to the respective flash lamps. In a case where a surface including two central axes of the two flash lamps arranged one at each end is defined as a standard surface, an acute angle against the standard surface is set to be decreased as the side part reflection surface is positioned closer to a center of the arrangement of the plurality of the flash lamps.

Flash fixing device and a printing device using the flash fixing device

Flash fixing equipment for fixing a toner image onto a medium by means of flashlight is to reduce non-uniformity of halftone image print density. Flash fixing unit has flash energy distribution consisting of a center zone and front/end zones. The flash frequency of the flash lamp is controlled so that the toner fixing start energy being subtracted from the added value of flash energies of front and end zones becomes substantially equal to the flash energy value on the center zone. The energy distribution exceeding the fixing start energy which affects print density (size of toner-overflowed area) is controlled to have a flat characteristic to reduce non-uniformity of print density.

An ink drop is injected via a nozzle by changing drive voltages applied to a piezoelectric element to reduce the volume of a pressure chamber filled with ink, so that the injected ink drop hits upon a print medium to carry out printing. Upon injecting the ink drop via the nozzle, an injection timing of the ink drop is changed corresponding to a drive frequency of the drive voltages using a predetermined rule. The predetermined rule may be a table defined in terms of drive frequencies of the drive voltages and optimum injection timings of the ink drop corresponding to the drive frequencies.

Inkjet printing method and device

A halftone printing is realized by jetting ink drops of mutually different sizes toward a print medium. Among them, the ink drop having the middle size is set to be a reference ink drop for determining injection timings of the ink drops. When the ink drop to be jetted is bigger than the reference ink drop, an injection timing thereof is delayed relative to that of the reference ink drop. On the other hand, when the ink drop to be jetted is smaller than the reference ink drop, an injection timing thereof is advanced relative to that of the reference ink drop. This allows all the ink drops to be hit upon the print medium precisely at given positions.

The instant invention has an exemplified object to provide an inkjet head and recording device having such an inkjet head with a simpler structure as achieves higher quality of printing inexpensively than the conventional. The pressure-chamber plate of this invention is slit or divided into a plurality of elements.
