Claims
- 1. A toner composition for electrostatic latent image development used in flash fixing, comprising:a binder resin, a colorant and a charge control agent, wherein a concentration of benzene generated by heating said toner composition for 90 seconds at 330° C. is no more than 60 μg/g.
- 2. The toner composition for electrostatic latent image development used in flash fixing according to claim 1, wherein the concentration of the benzene generated is no more than 40 μg/g.
- 3. The toner for electrostatic latent image development used in flash fixing according to claim 1, wherein the binder resin is a polyester resin.
- 4. The toner for electrostatic latent image development used in flash fixing according to claim 1, wherein the toner is positively chargeable.
- 5. The toner for electrostatic latent image development used in flash fixing according to claim 1, wherein the charge control agent is a nigrosine type compound.
- 6. The toner for electrostatic latent image development used in flash fixing according to claim 1, wherein the charge control agent is a quaternary ammonium salt compound.
- 7. The toner for electrostatic latent image development used in flash fixing according to claim 1, wherein the charge control agent is a triphenylmethane type compound.
- 8. A toner composition fixing method, comprising:selecting the toner according to claim 1, wherein the charge control agent is selected from the group consisting of quaternary ammonium salt compounds, triphenylmethane type compounds and nigrosine type compounds which have been vacuum heat-treated at a temperature of at least 100° C. but no more than 250° C. under a degree of vacuum of 0.02 MPa or lower; and using the toner in flash fixing.
