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.

摘要： An image forming method comprises the steps of feeding a magnetic toner onto a toner carrying member, wherein the magnetic toner comprises a binder resin and a magnetic powder with a volume average particle diameter ranging from 7 .mu.m to 10 .mu.m, and the magnetic toner particles have a quantity of triboelectric charge which satisfies the following expression:0.1.times.A+2.ltoreq.-Q.ltoreq.0.1.times.A+16.The magnetic toner is triboelectrically charged to impart a negative triboelectric charge to the magnetic toner. An electrostatic latent image is formed on a latent image carrying member by using the magnetic toner to form a toner image. Thereafter, the toner image is transferred to a transfer medium.
