Abstract (en)
[origin: EP0747774A2] An electrophotographic toner comprises a polyester resin and an electric charge control resin have a functional group which enables the toner to be positively charged. The polyester resin has an acid value of not more than 10 mgKOH/g and a hydroxyl value of not more than 40 mgKOH/g, and the functional group is present in a proportion of 2 to 5 mol % in the electric charge control resin. The invention also concerns a contact development method using this toner with a single-layer positive charge type organic photoconductor to visualise an electrostatic latent image as a toner image. <IMAGE>
