TONER WHICH HAS NO IMAGE PROBLEMS INCLUDING ANTI-OFFSET PROPERTY AND BLURRING IN A HIGH-TEMPERATURE AND HIGH-HUMIDITY ENVIRONMENT AFTER USING FOR A LONG TIME

摘要

PURPOSE: Toner is provided to obtain enough image density by using a small amount of the toner, and to prevent image problems of anti-offset property and blurring in a high-temperature and high-humidity environment.;CONSTITUTION: Toner contains a binding resin, a pigment, and an azo compound. The azo compound contains a polymer component, and other parts except for the polymer component are denoted by chemical formula 1. If the solubility of the azo compound is A and the solubility of the binding resin is B in a toluene-hexane dissolubility test, A and B satisfies B-A=60.;COPYRIGHT KIPO 2013
