An imaging system includes: a conveyor belt that conveys a medium having a toner image fixed thereto, along a conveying route; a heating element to heat the conveyor belt; and a pressing roller to press the conveyor belt against the heating element. The heating element may have a planar surface adjacent to an inner peripheral surface of the conveyor belt.

Various variable gloss reduction techniques are disclosed. In one embodiment, a gloss reduction technique is disclosed using a textured roller and a wiper impregnated with fuser oil to create a differential gloss pattern that reduces the gloss of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a combination of heat and pressure to create a differential gloss pattern that reduces the gloss in specific regions of an image printed on a substrate. In one embodiment, a gloss reduction technique is disclosed using a differential gloss pattern to generate a security mark on a printed image to prevent against copying or fraudulent misrepresentation of the image.

In an image heating apparatus, a region of a recording material, on which an image can be formed, is divided into a boundary region and a non-boundary region so as to correspond to a plurality of heating elements. The boundary region includes a boundary between one heating element out of the plurality of heating elements and an adjacent heating element thereof, and overlap with the one heating element and the adjacent heating element overlap in a predetermined range in the orthogonal direction. The non-boundary region overlaps with the one heating element in a range other than the boundary region. A control target temperature of a heating region that is heated by the one heating element is set to a higher temperature of a first temperature based on information corresponding to the boundary region, and a second temperature based on information corresponding to the non-boundary region.

An apparatus includes a resolving unit configured to resolve input image data into image data for each frequency band, an acquisition unit configured to acquire skewness corresponding to the resolved image data resolved by the resolving unit, wherein the skewness is acquired from a histogram corresponding to each of the resolved image data, and an adjustment unit configured to determine image data to be processed, out of the resolved image data based on the acquired skewness acquired and perform gain adjustment on the determined image data.

An image heating apparatus includes first and second heat generating elements arranged adjacent to each other, and a control portion that controls power supplied to the first and second heat generating elements, and that is capable of individually controlling the first and second heat generating elements, the first and second heat generating elements being respectively controlled so as to maintain a control temperature. When an image exists in a second region on the recording material heated by the second heat generating element, and an image does not exist in a first region on the recording material heated by the first heat generating element, the control portion sets the control temperature of the second heat generating element, when heating the second region, in accordance with a distance between an end section of the image in the second region and a boundary of the first region and the second region.

An image forming apparatus sets, in a case where a mode for executing a heating process a plurality of times is set, a target temperature of a fixing unit during a second heating process depending on image information about a toner image to be formed on a first surface of a recording medium immediately before a first heating process.

A method, a system and a recording medium for rendering a macro gloss effect using a digital front end processor and a color printer having color marking materials involve defining a vector pattern cell, and creating a pattern ink based on the vector pattern cell. The pattern ink can be constrained to write at or near an ink limit at small sizes varying from a high toner pile to a lower toner pile within a pattern ink cell based on the vector pattern cell. One or more objects and a background can be then painted with the pattern ink to create a macro gloss effect image based on the pattern ink.

An image post-processing method includes a glossiness control step of irradiating a fixed toner image with a glossiness control light. The toner image is formed with a toner containing a compound that absorbs light. The glossiness control light is capable of at least reducing a glossiness of the fixed toner image. The glossiness control light has a maximum emission wavelength in a wavelength region which is absorbed by the compound.
