Abstract
Disclosed is a toner for flash fixation which comprises: (i) a resin containing (a) a low molecular weight compound having the peak of molecular weight in 3,000 to 60,000 by gel permeation chromatography (GPC) and (b) a high molecular weight compound having the peak or shoulder of molecular weight in 80,000 to 1,000,000 by GPC, with the weight ratio of the low molecular weight to the high molecular weight compound in the range of 97 to 60/3 to 40 and (ii) a coloring material or a toner for flash fixation which comprises (i) a resin containing (a) a low molecular weight compound having the peak of molecular weight (Lp) in 3,000 to 60,000 by GPC, (b) a middle molecular weight compound having the peak of molecular weight (Mp) in 5,000 to 100,000 by GPC and (c) a high molecular weight compound having the peak of molecular weight (Hp) in 80,000 to 1,000,000 by GPC, with the condition of Lp<Mp<Hp and (ii) a coloring material, and a method for fixing a toner by flash fixation using these.
