摘要： Toner characterized in that assuming that the glass transition point of the toner measured by a differential scanning calorimeter (DSC) is represented by T1 (° C.), in a micro compression test at T1−10 (° C.), when a load from 0.00 N (0.00 mgf) to 7.85×10−4 N (80.00 mgf) is applied at the intervals of 7.85×10−7 N (0.08 mgf) to a single particle of the toner, the strain value A80a (%) at 7.85×10−4 N is 35.0 to 75.0%; and in a load (x-axis)-strain (y-axis) curve obtained by the micro compression test, the ratio of an area (S1a) of a specific region, relative to an area (S2a) of a specific region, (S1a/S2a), is 1.5 to 3.5.

摘要： The image forming apparatus has an image forming portion capable of forming an image on a transferring medium by the use of a hypochromatic toner and a hyperchromatic toner of substantially the same color. The image forming portion is provided with a developing device for developing with the hypochromatic toner and the hyperchromatic toner, wherein, in an image area in which the hyperchromatic toner and the hypochromatic toner are mixedly present, the recording rate of the hyperchromatic toner is 1/16, the minimum size Wmini of a toner image of the hyperchromatic toner is 50 μm or less on the transferring medium. Thereby, it is achieved to reduce graininess.
