Title:
ELECTROSTATIC CHARGE IMAGE DEVELOPMENT TONER
Document Type and Number:
Japanese Patent JP2012022171
Kind Code:
A
Abstract:

To provide an electrostatic charge image development toner with good fixability and excellent heat resistant storage property and separability.

An electrostatic charge image development toner is used which includes a toner base particle containing a binding resin, a mold release agent and a colorant. The toner satisfies the following formula (1) Tg<Tw<Ts when the temperature depending curve of a storage elastic modulus G' of the toner has a shoulder S. The temperature of the shoulder is expressed by Ts and the glass transition temperature of the toner measured by a differential scanning calorimeter is expressed by Tg, and the maximal heat absorption peak temperature of the toner measured by the differential scanning calorimeter is expressed by Tw.
