ABSTRACT:
Bipolar liquid electrostatic developer consisting essentially of at least one charge director in a nonpolar liquid having dispersed therein two toner particles having opposite charge polarity which comprise at least one thermoplastic copolymer resin. The particle average by area size is less than 10 .mu.m. The ratio of the two toner particles is 5 to 95 and 95 to 5. A process of simultaneous transfer of such developer is included. The developer is useful in copying.
