Branched polyarylene ether polymers comprising a plurality of branch points, each branch point being of the formula ##STR00001## wherein each Ar is an aryl moiety or an alkylaryl moiety, provided that when Ar is an alkylaryl moiety at least three of the repeating groups are bonded to an aryl portion thereof through the oxygen atoms in the repeating groups, each x, independently of the others, is an integer of 3 or greater, each m, independently of the others, is an integer of 0 or 1, each D, independently of the others, is either (a) another branch point, (b) a terminal group, or (c) of a defined formula. Also disclosed are imaging members containing these polymers.
