ABSTRACT:
A binder resin which forms a resin powdery product such as a toner for developing electrostatic latent images. The binder resin comprises a biodegradable resin comprising a polyhydroxyalkanoate produced by culturing a microorganism and having as a specific monomer unit a 3-hydroxyalkanoic acid such as 3-hydroxy-5-phenylvaleric acid. This binder resin has very good properties as a binder resin and also has a high safety to human bodies and environment. Also disclosed are a toner for developing electrostatic latent images which contains such a binder resin, and an image-forming method and an image-forming apparatus which make use of the toner.
