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.

Provided is a powder pasting device for pasting powder on an image pattern formed on one main surface of a recording medium, the powder pasting device includes: a powder holding member having a powder holding surface holding powder by sticking; a powder supplying member that supplies powder to the powder holding surface; a rubbing member that rubs the powder holding surface to which powder has been supplied from the powder supplying member; and a facing member that is disposed at a position facing the powder holding surface of the powder holding member, sandwiches a recording medium having an image pattern functioning as an adhesive between the powder holding surface and the facing member, and thereby transfers the powder held on the powder holding surface by sticking onto the image pattern.

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.

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.

The present invention provides an image forming method for forming a decorated image having a resin layer and a powder contacted with each other, the method including: forming a resin layer on a recording medium; and supplying a powder onto the recording medium, in which the recording medium has a surface with an arithmetic mean height Sa of 1.000 or more.

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 device includes: a fixing unit that fixes an image formed on a recording medium; a heating unit that heats a recording medium that has been subjected to a fixing process by the fixing unit; and a controller that sets a glossiness of an image on a recording medium, wherein the controller controls a heating amount with the heating unit depending on the set glossiness.

An image forming apparatus includes a reception unit to receive a job, heating and pressing rotary members to form a nip portion, and a spraying member having a nozzle and a cylinder. The nozzle discharges air to the heating rotary member and a recording material. During a period after the reception unit receives the job and before a leading edge of a first sheet of the recording material reaches the nip portion, the spraying member performs a spraying operation of spraying air in an amount greater than or equal to a predetermined amount. The air that the spraying member sprays on the first sheet of the recording material during the job is higher in temperature than the air that the spraying member sprays during the period after the reception unit receives the job and before the leading edge of the first sheet of the recording material reaches the nip portion.
