MAGNETIC ONE-COMPONENT TONER, AND IMAGE FORMING METHOD AND IMAGE FORMING APPARATUS USING SAME

摘要

PROBLEM TO BE SOLVED: To provide a magnetic one-component toner capable of preventing the occurrence of a long-cycle development ghost in a magnetic one-component development system using a resin coated developing roll.

SOLUTION: The magnetic one-component toner contains a binder resin and a magnetic material and is used in a development method of forming a toner image by applying an AC electric field to the developing roll the surface of which is covered with the resin and into which a magnet is incorporated while the toner is formed in a layer form to cause the transplantation of the toner from the developing roll surface to the latent image portion formed on the latent image carrier surface separately arranged to face the developing roll. The adhesion by a centrifugal method is ≤25%.
