A toner formed of at least a binder resin, a colorant, a charge control agent
and
a wax, is provided with a uniform state of dispersion of the wax and good balance
of low-temperature fixability and anti-high-temperature offset characteristic,
while exhibiting good developing performances over wide environmental conditions.
The toner is characterized in that (a) the binder resin comprises a hybrid resin
component having a polyester unit and a vinyl polymer unit, (b) the toner exhibits
a loss tangent (tan ) of 1.0 at a temperature in a range of 80-160
C., and (c) the toner provides a DSC curve showing a heat-absorption peak in a
temperature range of 85-130 C. on temperature increase as measured according
to differential scanning calorimetry (DSC).
