Photoresponsive low-molecular weight material, adhesive, toner, and image forming method

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.

Image post-processing method, image post-processing apparatus and image forming apparatus

A toner includes toner particles, wherein the toner particles contain a polymer containing a structural unit derived from an azobenzene derivative having a polymerizable group.

Toner and image forming method

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&#xb0; 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.

Image post-processing method and apparatus for emitting a glossiness control light, and image forming apparatus

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.
