Title:
TONER FOR DEVELOPING ELECTROSTATIC CHARGE IMAGE AND IMAGE FORMING METHOD
Document Type and Number:
Japanese Patent JP3945167
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a toner for developing an electrostatic charge image which is adaptive to oilless fixation, having offset resistance, without causing filming on a photoreceptor and improved in fluidity.
SOLUTION: In the toner for developing an electrostatic charge image containing at least resin, colorants and crystalline substances, toner particles have sea island structure; and the average value of the Feret's horizontal diameter of a part corresponding to an island is 200 to 900 nm, and the coefficient of variation for the Feret's horizontal diameter is ≤40%.
