Pressure-fixable capsule toner comprising pressure fixable core material and vinyl polymer shell material |
摘要 |
A pressure-fixable capsule toner for electrophotography having characteristics such as good combination of fixability and durability and also a stable charge controlling characteristic is provided. The core materials typically are of polyethylene or paraffin wax. The shell material is a vinyl polymer characterized by low molecular weight distribution represented by a ratio of weight-average molecular weight/number average molecular weight of not larger than 3.5. The vinyl polymer is preferably a copolymer of styrene or a derivative thereof and a tertiary amino-group containing vinyl monomer.
