<p>PROBLEM TO BE SOLVED: To provide a toner for electrophotography that can achieve both low-temperature fixability and heat-resistant storage property at high level, and can provide high-quality images with excellent abrasion resistance and less image conveyance damage and void images.SOLUTION: A toner for electrophotography is a toner that includes at least a block copolymer composed of a crystalline segment and amorphous segment as a binder resin, and has a maximum elastic stress value (ES100) of 2.0×10to 8.0×10Pa at a distortion amount of 200%, which is obtained by measuring at 100°C by a LAOS method (Large Amplitude Oscillatory Shear Flow), and a maximum elastic stress value (ES70) of 2.0×10to 6.0×10Pa at a distortion amount of 200%, which is obtained by decreasing the temperature from 100°C to 70°C and measuring at 70°C.</p> |
