Title:
TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP3817348
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a toner for developing an electrostatic charge image having satisfactory low-temp. fixability, anti-offsetting property and blocking resistance independently of transfer paper.
SOLUTION: This toner contains a binder resin, a colorant and wax. A temp. at which the ratio (G''/G'=tanδ) of the modulus of lost elasticity of this toner to the modulus of storage elasticity becomes 1.0 exists in the range of 55-70°C, and at the temp. the modulus of elasticity is ≤1.5×108Pa. The ratio (G'40/G'50) of the modulus (G'40) of storage elasticity of this toner at 40°C to the modulus (G'50) of storage elasticity at 50°C is 1.5-5.0, the ratio (G'50/G'60) of the modulus (G'50) of storage elasticity at 50°C to the modulus (G'60) of storage elasticity at 60°C is 3-20, the ratio (G'70/G'100) of the modulus (G'70) of storage elasticity at 70°C to the modulus (G'100) of storage elasticity at 100°C is 50-250 and the ratio (G'110/G'140) of the modulus (G'110) of storage elasticity at 110°C to the modulus (G'140) of storage elasticity at 140°C is 2-20.
