<p>PURPOSE:To provide a color toner and an image forming method using the same, which is capable of attaining excellent transmissivity by forming a toner image on a transparent supporting body for overhead projector, has strength to prevent the generation of the embedment of an external additive even in the toner having a small particle diameter and is capable of preventing the generation of hot off-set in fixing by adding a releasing agent to the toner, does not requires coating a fixing roller with a silicone oil and is capable of increasing the durability of the fixing roller, by providing a highly releasable coating film layer composed of a fluororesin on the surface material of the roller. CONSTITUTION:(1) The electrophotographic image developing toner contains a bender and a coloring agent and satisfies following relation between volume average particle diameter Dv (mum) and storage elastic modulus G'170(dyne/cm<2>) at 170 deg.C -(2/15)Dv+3.5<=logG'170<=-(3/15)Dv+5.5. (2) The forming method of electrophotographic image includes a process for forming the toner image by developing the electrophotographic image with the electrophotographic image developing toner and a process for fixing the toner image with the fixing roller coated with a fluororesin layer.</p> |
