Polymerized toner

Enables High-Quality Printing, Saving Energy and Conserving Resources

A Next-Generation, High-Performance Toner Created through Chemical Reaction

Polymerized toner is a high-performance toner produced by chemically combining a resin with color pigment particles. Unlike conventional pulverized toner, which is made by crushing lumps of plastic into small particles, the polymerized method enables precise control of the structure of each toner particle. This, in turn, makes it possible to tailor the size and shape of each particle and impart various properties to it.
The polymerized toner developed by Konica Minolta achieves a print product that exhibits a high-quality image while reducing environmental impact. The Group is continually working to upgrade its polymerized toner to realize an ever higher quality product.

Simitri is the trademark for Konica Minolta polymerized toner. The term “Simitri” was coined from the word symmetry.

Polymerized Toner Saves Energy and Conserves Resources When in Use

When printing images using MFPs and printers, the process of fusing the toner with heat and fixing it to paper consumes the most electricity. The small and uniform polymerized toner particles conduct heat more efficiently than pulverized toner particles, and their low fusing point also means that less electricity is consumed during the fusing process.
In an effort to achieve greater power savings through the performance of low-temperature fusing, Konica Minolta developed a new type of polymerized toner, Simitri HD toner. This product features a core-shell configuration comprised of a thin outer layer of hard resin wrapped around a soft core of inner resin, to enable fusing at a lower temperature while also offering the thermostability required for high-speed printing. With such characteristics, polymerized toner has been adopted and used in many of Konica Minolta MFPs and printers.
The small size of polymerized toner particles also helps reduce the amount of toner consumed when printing the image. Thus Konica Minolta's polymerized toner products not only save energy, but also conserve resources.

Reducing Petroleum Resource Usage by Adopting Plant-based Biomass Material

Since first manufacturing polymerized toner in 2000, roughly 9% of the raw material used to make Konica Minolta toners has been plant-based biomass.*1
Konica Minolta polymerized toner contains wax dispersed evenly during manufacturing, thereby realizing oil-free fixing*2 when printing. By using plant-based materials for the wax component in all colors of toner-cyan, magenta, yellow, black-it reduces the use of materials derived from petroleum, a finite resource.

Biomass: Renewable bio-organic resources other than fossil-derived resources.
*2
Oil-free fixing: This is a way to exfoliate toner from the roller and fix it to the paper without using oil applied to a heat roller. It enables higher quality output by suppressing unwanted glare and blur in the image.

Simple Manufacturing Methods Greatly Reduce CO2, SOx, and NOx Emissions

Producing pulverized toner entails an involved process for crushing after making the lumps of plastic and consumes a great amount of energy for pulverization. It produces irregular sized particles which need sorting, and also results in lower production yields.
Polymerized toners, on the other hand, entail a relatively simple manufacturing process using chemical synthesis to make the toner particles. This reduces energy consumption and also ensures uniform particle size, which minimizes the sorting needed. Compared to pulverization methods, these advantages help to reduce generation of CO2 and the acid-rain causes SOx (sulfur oxide) and NOx (nitrogen oxide), thereby significantly reducing environmental impact.
