PURPOSE:To obtain an electrophotographic wet type toner superior in pressure transfer performance, and adhesion between the toner and a lithographic plate of aluminum or the like, by dispersing olefinic resin particles having carbonyl groups into an electrically insulating liquid. CONSTITUTION:An electrophotographic wet type toner is prepared by dispersing (B) olefinic resin particles, such as ''N-Polymer '' made by Nippon Sekiyu Kagaku KK having about <=10mum paticle diameter and carbonyl groups into (A) an electrically insulating liquid, such as an iso- or n-paraffinic hydrocarbon. Said toner image can be transferred with pressure to an insulating transfer material, such as paper, by an ordinary method, and moreover, it can be efficiently transferred even onto a conductive transferred image-receiving material made of metal or the like, thus permitting superior transfer performance to be exhibited by use of a photoreceptor provided with a layer of an easily strippable material on the surface as an electrophotographic receptor. |
