Abstract
A toner which includes a binder resin, a colorant and a hydrocarbon wax has a ratio W1/W2 of the half width W1 (° C.) of a endothermic peak derived from melting of the hydrocarbon wax in a first temperature rise process on the toner to the half width W2 (° C.) of a endothermic peak derived from melting of the hydrocarbon wax in a second temperature rise process, as measured with a differential scanning calorimeter, with the ratio W1/W2 being not less than 0.50 and not more than 0.90.
