Abstract:
A toner for developing electrostatic charge images in which offset phenomenon and winding phenomenon do not occur in a wide temperature range, even if the binding resin contains the alicyclic olefinic resin, that is, a toner for developing electrostatic charge images which is superior in fixability in a high temperature range, and which is superior in melt contamination resistance, is provided.In the toner for developing electrostatic charge images comprises at least binder resin and colorant, the binding resin containing alicyclic olefinic resin (A) and thermoplastic elastomer (B). It is preferable that the alicyclic olefinic resin (A) be a copolymer comprising cyclic olefin (A1) and an acyclic unsaturated monomer (A2) as an element. Additionally, it is preferable that the melting point of the thermoplastic elastomer (B) be 60 to 190° C.
