    Abstract: A toner based on fly-ash rich carbon and method of producing are disclosed. The process includes preparing a latex and preparing a pigment including fly ash, where the fly ash has been ground to nanoparticle size. The latex, pigment including fly ash, and polyethylene wax are combined in an emulsion aggregation process. The latex is formed by a mixing process including combining ammonium bicarbonate, sodium dodecylbenzene sulfonate, styrene, acrylic acid, and methyl methacrylate. The emulsion aggregation process includes steps of dispersing a mixture of the polyethylene wax, pigment including fly ash, and latex in water, adding zinc oxide, nitric acid, adding Ethylenediaminetetraacetic acid (EDTA), elevating the temperature, neutralizing the product mixture with NaOH solution and cooling the mixture, Centrifuging, washing and drying are performed to achieve a finished toner which includes fly ash pigment, polyethylene wax, poly(styrene-methyl methacrylate-acrylic acid) latex, zinc oxide and a chelating agent.

    Abstract: An image formation apparatus according to an embodiment may include: a first image formation unit including a storage part and configured to form a glitter developer image; and a controller configured to control the first image formation unit, upon forming a glitter image on a medium based on predetermined print data when a remaining amount of a glitter developer in the storage part is a first remaining amount, to form the glitter developer image with a ratio of the glitter image per unit area being a first area ratio, and upon forming the glitter image on the medium based on the predetermined print data when the remaining amount is a second remaining amount less than the first remaining amount, to form the glitter developer image with the ratio of the glitter image per unit area being a second area ratio greater than the first area ratio.
