Abstract

A flexible electrophotographic imaging member including a supporting substrate coated with at least one imaging layer comprising charge transport material free of long chain alkyl carboxylate groups and a small amount of a different second hole transporting material containing at least two long chain alkyl carboxylate groups dissolved or molecularly dispersed in a film forming binder and coated from a mixture of solvents containing low boiling component and a small concentration of high boiling solvent. Preferably, the flexible electrophotographic imaging member is free of an anticurl backing layer, the imaging member comprising a supporting substrate uncoated on one side and coated on the opposite side with at least a charge generating layer and a charge transport layer containing comprising a first charge transport material and a small amount of a different second hole transporting material containing at least two long chain alkyl carboxylate groups dissolved or molecularly dispersed in a film forming binder and coated from a mixture of solvents containing low boiling component and a small concentration of high boiling solvent.
