ABSTRACT:
A process for changing layered imaging members by the transfer of ions thereto which comprises contacting the imaging member with a liquid developer comprised of a nonpolar liquid, and a mixture of surfactants of an ammonium block copolymer first surfactant of the formula ##STR1## wherein X.sup.- is a conjugate base or anion of a strong acid; R is hydrogen or alkyl; R' is alkyl; R" is an alkyl group containing from about 6 to about 20 carbon atoms; and y and x represent the number average degree of polymerization (DP) wherein the ratio of y to x is in the range of from about 10 to 2 to about 1,000 to 200; and a second surfactant component of the formula ##STR2## wherein R.sub.1 is selected from the group consisting of hydrogen and alkyl, and n is 0 (zero), 1, 2, 3, or 4.
