More Information
Summary:An electrophotographic toner excellent in dispersibility of a colorant, excellent in fixing property at a low temperature and having a broad fixing latitude of good offset resisting property, and a process for producing the same, as well as an electrophotographic developer and a process for forming an image using the electrophotographic toner are provided. The electrophotographic toner is provided that contains a binder resin and a colorant, in which the binder resin contains a crystalline polyester containing a carboxylic acid of two or more valences having a sulfonic acid group as a monomer component, and a process for producing the same, as well as an electrophotographic developer and a process for forming an image using the electrophotographic toner are provided.
