摘要： A toner for developing an electrostatic image includes a binder resin, a colorant and a wax. The toner shows heat-absorption characteristics represented by a DSC heat-absorption curve obtained on temperature increase in a temperature range of 30-150.degree. C. by a differential scanning colorimeter (DSC). The DSC heat-absorption curve shows a maximum heat-absorption peak (P1) in a temperature range of 70-90.degree. C. The DSC curve also provides a differential curve showing a first maximum (Max1) on a lowest temperature side at a temperature (T1) of 50-65.degree. C., showing a second maximum (Max2) on a next lowest temperature side at a temperature (T2) of 65-85.degree. C., and showing a minimum (Min1) on a highest temperature side at a temperature (T3) of at least 95.degree. C. Because of the DSC heat-absorption characteristics, the toner exhibits excellent fixability (including anti-offset characteristic) over a wide temperature range and excellent continuous image forming characteristic.

The toner may be further blended with an organically treated inorganic fine powder to provide a developer. The toner or developer retains good lubricity and releasability so that it is suitable to be used in an image forming method including means contacting a latent image-bearing means, such as a contact charging means, a contact transfer means or a contact cleaning means.
