Provided is an electrophotographic toner which has a wide fixing temperature range, and is excellent in offset resistance and blocking resistance as an electrophotographic toner used in an image forming method which is circulated and reused in a developing device. According to one aspect of the present invention, a wax, which is one of the constituent materials of a toner, comprises one or more of a long-chain alkyl alcohol or an amine or a fluoroalkyl alcohol or an amine (a), and an unsaturated compound. A waxy product (I) obtained by reacting a polyvalent carboxylic acid or its anhydride (b) with a synthetic hydrocarbon wax (c) having a melting point of 50 to 150 ° C., said waxy product (I) In the DSC curve, the toner for electrophotography has at least one endothermic peak in the range of 60 ° C to 110 ° C.
