Abstract:
A toner comprising toner particles comprised of at least one binder, at least one colorant, and optionally one or more additives,wherein following triboelectric contact with carrier particles, the toner has a charge per particle diameter (Q/D) of from âˆ’0.1 to âˆ’1.0 fC/&mgr;m with a variation during development of from 0 to 0.25 fC/&mgr;m and the distribution is substantially unimodal and possesses a peak width of less than 0.5 fC/&mgr;m and the toner possesses a charge to mass ratio (Q/M) of from âˆ’25 to âˆ’70 &mgr;C/g with a variation during development of from 0 to 15 &mgr;C/g, and wherein the toner has a melt viscosity ranging from 4.0Ã—103 to 1.6Ã—104 Poise at a temperature of 116Â° C., and from 6.1Ã—102to 5.9Ã—103 Poise at a temperature of 136Â° C.
