Method of forming fixed images

A method of forming fixed images, comprising applying a two-component developer comprising a carrier and a toner comprising a wax and a resin binder comprising a crystalline polyester to a two-component development device with a linear speed of from 500 to 5,000 mm/sec, to develop the toner,

• wherein the crystalline polyester is contained in an amount of from 3 to 40% by weight and the wax in an amount of from 2.5 to 10% by weight, of the toner, and wherein the two-component development device comprises at least three magnet rollers which are arranged closely to each other along the perimeter of a photoconductor, wherein one magnet roller arranged on the uppermost side in the rotational direction of the photoconductor rotates in a direction opposite to the rotational direction of the photoconductor at the point therebetween, and the other magnet rollers rotate in the same direction as the photoconductor at the point therebetween,
• wherein after printing 150,000 sheets, toner is fused to the surface of the carrier in an amount such that the difference in triboelectric charges (ΔQ/M) before printing and after printing said number of sheets is ± 4.5 μC/g, and
• wherein the carrier is a magnesium-based ferrite carrier coated with a resin comprising an acrylic resin and a fluororesin.
