ELECTROSTATIC CHARGE IMAGE DEVELOPING TONER, FULL COLOR TONER KIT, IMAGE FORMING METHOD, AND METHOD FOR MEASURING THERMALLY STIMULATED CURRENT

摘要

PPROBLEM TO BE SOLVED: To provide a toner excellent in stability of a charged state, ensuring little weakly charged or reversely charged toner, and free of toner scattering, even after output of several ten thousand images in an environment at high temperature and high humidity after long-time storage in an environment at high temperature and high humidity, excellent in stability of a charged state, ensuring little weakly charged or reversely charged toner, and free of surface stain (fogging), even after output of several ten thousand images in an environment at low temperature and low humidity as well as in an environment at normal temperature and normal pressure, and having satisfactory coloring property, light resistance, transparency, color developing property, sharpness, color reproducing property, saturation and gloss even after output of several ten thousand images, and to provide a developer, an image forming method and an image forming apparatus. PSOLUTION: In the electrostatic charge image developing toner including at least a colorant and a binder resin, a peak of thermally stimulated current value in at least the range of 60-100°C in a temperature up process is 0.001-1 pA, wherein the peak is measured by a contact process in which the toner is charged and measurement is performed while keeping the toner in contact with an electrode.
