摘要： An image forming method has developing an electrostatic latent image on an electrostatic latent image bearing member by the use of a toner containing a wax component, to form a toner image on the electrostatic latent image bearing member; transferring the toner image to the surface of a recording medium; and fixing the toner image on the recording medium, to the recording medium. The recording medium has a laminated film having a substrate layer and a wax component absorption layer for absorbing a wax component contained in the toner. The wax component absorption layer is formed of a resin capable of inhibiting crystal growth of the wax component. The wax component absorption layer is capable of absorbing the wax component contained in the toner when the toner image is fixed to the recording medium.

摘要： A color toner for developing electrostatic images is formed of color toner particles each including a binder resin, a polyalkylene, and a colorant. The color toner particles are formed by suspension polymerization. The polyalkylene is characterized by having a crystallinity of 10-50% and a melting enthalpy (as measured by a differential scanning calorimeter) of at most 35 cal/g. The color toner is characterized by an improved fixability without causing offset especially at a relatively low temperature and suitable for providing a transparency film for an overhead projection.
