MAGNETIC TONER

摘要

Provided is magnetic toner which has an excellent low-temperature fixation characteristic and can reduce contamination of a pressure roller even in various use conditions, which suppresses an image defect such as image irregularities so as to obtain a high-level image quality. The magnetic toner includes toner particles containing at least a bonding resin and a magnetic material. An activation energy Ea (kJ/mol) obtained from a shift factor aT120 in a master curve when the reference temperature is set to 120 degrees C of the toner and an activation energy Eb (kJ/mol) obtained from a shift factor aT150 in a master curve when the reference temperature is set to 150 degrees C of the toner satisfy Expression (1) given below, and Ea is not greater than 110 (kJ/mol). 1.00 = Ea/Eb < 1.20 (1)
