Abstract
There is disclosed a toner which comprises at least a binder resin, a coloring agent, and a wax and in which a deformation amount of the toner (R) at the time of application of a load of 200 g at a temperature of 120° C. is 45% to 75% and in which a deformation amount of the toner (R) at the time of application of a load of 500 g at a temperature of 120° C. is 65% to 85% and in which there is at least one endothermic peak or shoulder in a range at 60 to 120° C. in a DSC curve at the time of temperature rise measured by a differential scanning calorimeter (DSC). By the toner, an offset can be inhibited from being generated in heating/pressurizing/fixing in which an oil for preventing a high-temperature offset is not used or a use amount of the oil is reduced, and an OHP fixed image superior in transparency can be obtained.
