An electrostatic charge image developing white toner includes a white toner particle and a yellow toner particle that includes an organic yellow pigment, wherein a content ratio (by number) of the yellow toner particles to all of toner particles included in the toner is from 0.01% by number to 3% by number.

Print glossing is described. Print glossing can be performed on a glossing drum having a location affixed to a circumferential outer surface thereof, where the location transits from a first position in an apparatus having a first temperature range selected to enable reflow of ink applied to a substrate that is placed at the location to a second position in the apparatus having a second temperature range selected for clean release from the location of the ink applied to the substrate.

An image forming apparatus includes a first image forming unit that forms a metallic-color toner image having a metallic color, a second image forming unit that forms a non-metallic-color toner image having a color different from the metallic color, and a transfer unit that transfers the toner images onto a recording material so that the non-metallic-color toner image is superimposed on an upper side of the metallic-color toner image on the recording material.

An imaging system with a gloss treatment device includes an endless belt, a heating portion and a pressing portion. The endless belt conveys a medium along a conveyance direction. The heating portion heats the endless belt. The pressing portion presses the endless belt against the heating portion. A nip is formed in a region where the endless belt contacts both of the pressing portion and the heating portion. The nip includes an upstream end and a downstream end in the conveyance direction, and a reference line intersects the upstream end and the downstream end of the nip. The endless belt includes a conveyance portion that is inclined toward the heating portion, in relation to the reference line associated with the nip.

An imaging system includes a toner transfer device, a leveling device and a glossing device. The toner transfer device transfers gloss toner to a surface of a medium. The leveling device levels a layer of the gloss toner on the surface of the medium. The glossing device performs a re-melting process and a cooling process on the medium after the layer of the gloss toner has been leveled.

An image forming apparatus comprises an image forming section which forms an image on an image receiving medium with a color material; a heating member which heats the image receiving medium; a heater which heats the heating member; a sensor which detects a temperature of the heating member; and a controller which executes a print job for forming an image on the image receiving medium with the image forming section and fixing the image on the image receiving medium with the heating member and a decoloring job for decoloring the image on the image receiving medium with the heating member and interruptedly executes an executable job in a state of stopping output of the heater if the temperature of the heating member is higher than a temperature control range of a job of which priority is highest and there is the executable job at the temperature of the heating member.

An image processing apparatus includes: a determining unit configured to determine a parameter for image processing for a special toner plate depending on a type of a special toner other than a process color toner; and an image processing unit configured to process an image of the special toner plate using the determined parameter.

A brilliant toner includes release agent domains meeting conditions (1) a length of the release agent domain in a longitudinal axis direction is 300 nm to 1,500 nm, (2) a ratio between the length in the longitudinal axis direction and in a short axis direction of the release agent domain is 3.0 to 15.0, (3) an angle between (a) a tangent line passing through a contact point of (a1) a circumference of a circle that is centered at a centroid of the release agent domain and is inscribed in an outer edge of the toner particle and (a2) the outer edge and (b) a line passing through the centroid and extending in the longitudinal axis direction is 0° to 45°, and (4) a ratio of a distance between the centroid and the contact point to an equivalent circle diameter of the toner particle is 0.03 to 0.25.

In an image forming apparatus, a controller performs processes in accordance with an operation mode settable to one of a first subscription mode and a second subscription mode. The first subscription mode corresponds to a first subscription in which a specific-color cartridge is a subscription subject and a non-specific-color cartridge is not the subscription subject. The second subscription mode corresponds to a second subscription in which both the specific-color cartridge and the non-specific-color cartridge are the subscription subject. The controller performs restricting usage of the non-specific-color cartridge in a case where the first subscription mode is set as the operation mode and the type information of the non-specific-color cartridge indicates the subscription type, compared to a case where the second subscription mode is set as the operation mode and the type information of the non-specific-color cartridge indicates the subscription type.

A decoloring apparatus includes a sheet conveying unit, a scanner, a decoloring unit, and a controller. The decoloring unit decolors the image on the sheet conveyed through the sheet conveying unit. The decoloring unit is positioned downstream of the scanner in a sheet conveying direction. A distance along the sheet conveying direction between the scanner and the decoloring unit is shorter than a length of a first predetermined sheet size and longer than a length of a second predetermined sheet size. A controller determines whether the sheet conveyed by the sheet conveying unit is the first predetermined sheet size or the second predetermined sheet size. The controller performs a mode limiting process if the sheet size is determined to be the first predetermined sheet size.
