Abstract

Multiple copies can be made from an electrophotographic copy by using a toner containing a volatile oil. The electrophotographic copy is not fixed after it has been developed. Instead, a copy sheet is brought into contact with the toner image. By applying heat or infrared radiation, the oil of the toner is transferred to the copy sheet, thus creating an oil image which is made visible by dusting it with a colored powder. When a dry developer is desired, the toner can take the form of microcapsules having the volatile oil contained in them. Alternately, an organosol can be used for liquid developing. With this latter type of development, the toner consists of droplets of the volatile oil, with or without a dye dispersed in it, and is dispersed in a nonpolar liquid carrier.
