ABSTRACT:
A liquid developer for electrostatic photography and a method of using it is disclosed. The developer is comprised of toner particles dispersed in a higher electrically insulating carrier fluid and at least one kind of aliphatic alcohol having 10 or more carbon atoms in an amount of 0.1 to 40 parts by weight per one part by weight of the toner particles. Even after repeated use the developer provides images having high quality and the sensitivity of the developer does not substantially change. The developer is preferably used in the production of electrophotographic offset printing plates.
