Title:
ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER
Document Type and Number:
WIPO Patent Application WO/2019/088620
Kind Code:
A1
Abstract:
An electrostatic charge image developing toner comprises a binder resin, a colorant, and wax. In a differential scanning calorimetry (DSC) curve associated with the electrostatic charge image developing toner, a melting point MP 2 is between 70 and 83 ºC, inclusive. In the DSC curve, a negative rate of change in heat flow dHF 21/dT defined between a temperature T 21 and a temperature T 22, is between -0.50 mW/ºC and -0.10 mW/ºC, inclusive, wherein T 21 and T 22 are lower than MP 2. In the DSC curve, a positive rate of change in heat flow dHF 22/dT defined between a temperature T 23, and a temperature T 24, is between 0.50 mW/ºC and 1.80 mW/ºC, inclusive, wherein T 23 and T 24 are higher than MP 2.
