PURPOSE:To obtain a toner superior in flash fixability and fixable without void by adding an inorganic filler for raising the melt viscosity in a fixing process in addition to a binder resin and a colorant. CONSTITUTION:The inorganic filler, preferably such as, an insulating inorganic filler except carbon black, for enhancing the melt viscosity of the toner in the fixing process is incorporated in the flash fixing toner for developing an electrostatic latent image in addition to the binder resin and the colorant, thus permitting the melt viscosity of the toner in the fixing process to be enhanced even in the case of using a prepolymer having good fixability due to its comparatively low molecular weight and its low melting point, and void phenomenon to be prevented. |
