发明名称 CRYSTALLINE POLYESTER-ADDED TONER
摘要 <P>PROBLEM TO BE SOLVED: To provide a toner and a developer having a superior low-temperature fixability and a good offset resistance, and capable of forming a high-quality image with good sharpness for a long period without contamination of a fixation device and an image. <P>SOLUTION: This toner contains a binder resin including a crystalline polyester resin and an amorphous polyester resin as a component. The crystalline polyester resin is detected at least two diffraction peaks within the range of 20&deg;<2&theta;<25&deg; by a X-ray diffraction measurement and has a melting point of 60&deg;C or higher and lower than 80&deg;C with a half value width of the both diffraction peaks at less than 1.0&deg;/2&theta;. <P>COPYRIGHT: (C)2012,JPO&INPIT
