PURPOSE:To enable flash fixing method using a color toner by using developing toner powder contg. a binder resin stable against the irradiation of flash light, a dye or pigment, and a specified ammoniumyl compd. CONSTITUTION:The developing toner powder contains (A) the binder resin contg. bisphenol A-epichlorohydrine type epoxy resin or a polyester resin in an amt. of >=80mol%, (B) a dye or pigment in an amt. of 1-10wt% of the toner, and (C) the ammoniumyl compd., in anamt. of 1-10wt%, represented by formula I or II, R being H, 1-12C alkyl, and X being SbF6 or ClO4, such as formula III or IV. An electrostatic latent image is developed with this color toner, the obtained toner image 1 is transferred to a transfer paper 2, and the flash light 3 emitted from a discharge tube, such as a xenon flash lamp, is irradiated on the other image to obtain a fixed image 4. |
