Abstract:
A method of forming fixed images, including the step of applying a two-component developer containing a carrier and a toner containing a wax and a resin binder containing 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. The method of forming fixed images according to the present invention forms excellent fixed images by, for example, development of a latent image formed in electrophotography, electrostatic recording method, electrostatic printing method, or the like.
