摘要：
The present invention provides an electrophotographic toner containing, as a fixing resin, a styrene-acrylic copolymer in which styrene content, molecular-weight distribution and acid value are specified. The electrophotographic toner of the present invention is improved in heat resistance by raising the glass transition temperature of the fixing resin, while assuring excellent low-temperature fixing properties and resistance to off-set.
