Magnetic toners in a hybrid-component developing system and full-color toners in a twocomponent
developing system have been investigated. Magnetic toners in different steps of Xerographic
processes were selected to measure the tribo-charge and the particle size distribution.
The average particle size of the residual toners is larger than that of the original toners, and the
toner with small particle size and large q/d value is eaiser to be developed. For color toners, the
mass per unit area are in the range of 1 ?g/cm2~ 3.5 ?g/cm2 and the value of charge-to-mass
ratio are in the range of 2 ?c/g~ 8.1 ?c/g.
