ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a minute electrostatic charge image developer capable of sufficiently preventing occurence of offset and lowering the lowest fixable temperature and reducing occurence of stains on carriers and an electrostatic charge image support and developing sleeves and the like at the time of using a binary developer and keeping the developer good in fluidity and forming visible images in a large number of times. SOLUTION: The electrostatic charge image developing toner is obtained by heat-melting each of fine binder grains and a colorant and wax grains together with each other and these wax grains are characterized by containing its ester component in an amount of >=20 weight % and having a penetration degree of <=4.
