Abstract (en)

[origin: EP0896253A1] The invention in this application relates to a toner composition for electrostatic latent image development which is characterized in that, in a toner composition comprising at least binder resin, colorant and charge control agent, to be used in a print forming method provided with a print fixing device which fixes the toner image on a recording medium by means of a light flash, the concentration of benzene generated by heating for 90 seconds at 330 DEG C is no more than 60 mu g/g, and the invention provides a toner composition for electrostatic latent image development which either extends the filter life or does not require the use of a filter.
