Abstract
There is provided a toner comprising a binder resin, a wax, a charge control resin and a colorant. As a result of gas chromatography analysis, a first total amount of components detected in a range of a peak detecting time of hydrocarbons having 5 to 9 carbons is 500 ppm or less in terms of styrene; a second total amount of components detected in a range of a peak detecting time of hydrocarbons having 10 to 18 carbons is 5,000 ppm or less in terms of styrene; and an amount of a component corresponding to a maximum peak of peaks of hydrocarbons having 10 to 18 carbons is 3,000 ppm or less in terms of styrene.
