An apparatus comprised of a charging component, a development component, a transport component, a photoconductive component, and a fusing component, and wherein the development component contains a toner comprising at least one binder in an optional amount of from about 85 to about 99 percent by weight, at least one colorant in an optional amount of from about 0.5 to about 15 percent by weight, and calcium stearate in an optional amount of from about 0.05 to about 2 percent by weight and wherein following triboelectric contact with carrier particles, the toner has a charge Q measured in femtocoulombs per particle diameter D measured in microns (Q/D) of from about -0.1 to about -1 fC/mum with a variation during development of from about 0 to about 0.25 fC/mum and wherein the distribution is substantially unimodal and possesses a peak width of from about 0.1 fC/mum to about 0.5 fC/mum and the toner possesses a charge to mass M, as measured in grams, ratio (Q/M) of from about -25 to about -70 muC/gram with variation of Q/M during development of from about 0 to about 15 muC/gram.
