摘要:
A toner for developing an electrostatic image, which is excellent in low-temperature fixing properties, the prevention of offsetting and uniform chargeability, and which comprises a colorant and a polyester resin modified with an ethyleneimine derivative.
摘要:
A toner for developing an electrostatic image comprising at least a colorant and a binder resin, characterized in that the main component of the binder resin is a polyester resin, and the polyester resin is containing a polymer prepared by reacting a polyester oligomer and at least one compound selected form the group consisting of long chain alcohols and long chain carboxylic acids which have 12 or more carbon atoms.
摘要:
Provided are a polyester resin for use in a toner binder which is excellent in terms of offset resistance and low-temperature fixability, which keeps triboelectric charge stability even in an environment of a high temperature and a high humidity, which has excellent durability, and which is used in a toner that gives vivid image characteristics, a process for producing the same, and a toner using the same. The polyester resin for use in the toner binder is formed by linking at least a part of the crosslinked low-molecular polyesters through a dicarboxylic acid used as a linking agent.
