摘要:
The present invention was investigated for the purpose of providing a binder resin for toner which is excellent in the low temperature fixing property which can cope with the development of high-speed copier machines, and is excellent in the offset resistance, blocking resistance, pulverizability and development durability. As a result, it was found that the purpose could be achieved by using, as a binder resin for toner, a resin that can be obtained from at least three different vinyl polymers with different molecular weight, contents of functional groups, and preferably from a crosslinking agent having the vinyl polymer structure, and that contains a specific gel component. This resin has excellent melting property at low temperatures, and has suitable performance as a material for toner and a toner in high-speed copier machines.
摘要:
An object of the present invention is to provide a binder resin for a toner which is excellent in fixing properties and offset resistance even when used in a high-speed copier and is also excellent in suitability for grindability, development durability and the like, and a toner for electrophotography. The binder resin for a toner comprises a resin which is obtained by mixing a vinyl polymer with a crosslinked resin obtained by reacting a vinyl polymer having a specific molecular weight and a specific content of a functional group with a crosslinking agent, and which has a specific gel portion. As a result, the above object has been achieved. A toner using the binder resin is excellent in performances including fixing properties and the like even when used in a high-speed copier. Even when continuously used for a long time in a copier, the toner gives electrophotographic prints with satisfactory reproduction.
