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 .delta.) of 1.0 at a temperature in a range
of 80-160.degree. C., and (c) the toner provides a DSC curve showing a
heat-absorption peak in a temperature range of 85-130.degree. C. on
temperature increase as measured according to differential scanning
calorimetry (DSC).
