A matte liquid toner suitable for use in a liquid toner printer, comprising a carrier liquid, toner particles comprising a resin and substantially uncolored additive particles of average diameter between 1 and 20 micrometers dispersed in the resin.

In the case where a sheet on which a transparent toner image is to be formed has low glossiness, when the transparent toner image is formed in an area in which a user wishes to partly lower the glossiness, the glossiness in the area in which the user wishes to lower the glossiness is increased. For that reason, a print as desired by the user cannot be obtained by fixing the transparent toner image in an area corresponding to the area in which the user wishes to lower the glossiness. In the case where the sheet to be subjected to printing is judged as low glossy paper, the transparent toner image is placed in an image formable area except for the area in which the user wishes to lower the glossiness.

A control apparatus configured to control an image forming system, in forming a transparent toner on a sheet having color toners formed and fixed thereon, applies a transparent toner on an area on which an image can be formed and which is other than an area that a user desires to reduce the glossiness thereof.

A matte liquid toner suitable for use in a liquid toner printer, comprising a carrier liquid, toner particles comprising a resin and substantially uncolored additive particles of average diameter between 1 and 20 micrometers dispersed in the resin.

There is disclosed an image post-processing method for adjusting glossiness of a fixed toner image. The image post-processing method includes a glossiness control step of, with a non-contact heating device, heating a toner image fixed to a recording medium so as to reduce glossiness of the toner image. The non-contact heating device is configured to heat the toner image fixed to the recording medium to a temperature which reduces the glossiness of the fixed toner image.

In a fixing device, a magnetic flux generated by a coil passes through a magnetic circuit made of a heat generating layer of a fixing member and a magnetic substance core. The magnetic substance core includes a plurality of main cores each having an elongated form along a circumferential direction of the fixing member and arrayed at intervals along a width direction of a sheet. The end row main cores have a second shape effectively closer to an outer peripheral face of the fixing member compared to a first shape possessed by the central row main cores so as to enhance density of the magnetic flux, which passes the magnetic circuit, more in end sections than in a central section with respect to width direction of the sheet.

A flaky, fine powder comprising a flaky substance as the base and silica particles covering the surface of the base, aimed at reducing the glossiness of the base caused by the irregular reflection of light on its surface and improving the slipperiness. In particular, the powder comprises a flaky base substance such as natural mica and silica particles deposited on the base surface, wherein the silica particles may be optionally further immobilized by the hydrolysate of alkoxysilane or silica gel. The flaky fine powder is produced either by the adding alkoxysilane to a dispersion containing a flaky substance and silica particles and hydrolyzing it, by adding a silicic acid solution to the dispersion and gelling it, or by adding a combination of alkoxysilane and silicic acid solution. The powder can be compounded with various ingredients and is particularly useful with cosmetics.

A method for producing a reduced-moisture-content-solvent ink composition includes reducing the moisture content of a pigment dispersion containing a metal pigment and a dispersion medium or an ink composition containing the pigment dispersion and an organic solvent by bubbling treatment using an inert gas having a water vapor content of 2.0 mg / L or less.

The inkjet recording method includes: a treatment liquid deposition step of depositing a treatment liquid containing an aggregating agent onto a surface of a coating layer of a coated paper having a base paper layer and the coating layer coating the base paper layer; and an ink deposition step of depositing ink onto the surface of the coating layer on which the treatment liquid has been deposited. In the ink deposition step, the ink is deposited onto the surface of the coating layer in a state where an effective pH of the aggregating agent on the surface of the coating layer is not lower than 1.67 and not higher than 7.0, and an effective pH of the aggregating agent in the coating layer is not lower than 0.1 and not higher than 1.7.

An image processing method includes a conversion step of converting input image data into ink color data corresponding to respective use amounts of one or more types of color inks and a clear ink. In the conversion step, the input image data is converted into ink color data so that the use amount of the clear ink used in ink color data using a black carbon-containing ink becomes equal to or larger than that of the clear ink used in ink color data using no black carbon-containing ink.

There is disclosed an image post-processing method for adjusting glossiness of a fixed toner image. The method includes a glossiness control step and a temperature control step. The glossiness control step is a step of, to a toner image formed of a toner containing a light absorbing compound and fixed to a recording medium, emitting glossiness control light so as to reduce or increase glossiness of the toner image. The temperature control step is a step of heating the toner image immediately before the light is emitted to the toner image such that the toner image has a surface temperature which is at least 20° C. lower than a softening temperature of the toner. The glossiness control light has a maximum emission wavelength in a wavelength range in which the compound absorbs light and is made to at least reduce the glossiness of the toner image.

An ink jet recording method is provided for a low or non-absorbable recording medium using a solution containing a colored ink, a clear ink, and an aggregating agent for aggregating constituents in the colored ink. The method includes: causing the solution containing the aggregating agent to adhere to the recording medium; and a main scanning in which the colored and the clear inks are ejected while relative positions of an ink jet head and the recording medium are changed to a main scanning direction, and a sub-scanning in which the relative positions of the ink jet head and the recording medium are changed to a sub-scanning direction. The main scanning involves a region where a recording region in which the colored ink is ejected in the main scanning and a recording region in which the clear ink is ejected in the main scanning overlap one another.

A transparent developer has a glass transition point of 63.0° C. to 66.0° C., both inclusive, and a melt temperature, indicative of a softening point by a 1 / 2 method, of 94.3° C. to 97.0° C., both inclusive.

The image forming method includes a recording step of recording an image on an image recording layer of an image recording medium according to image data, a material setting step of setting a coating film to be provided on the image recording layer according to glossiness data indicating glossiness of the image reproduced by the image data, a condition setting step of determining a condition of a surface processing of the coating film by considering the set coating film and according to the glossiness data, and a processing step of performing the surface processing of the coating film in accordance with the determined surface processing condition.
