Imaging member

An image forming device comprising at least a photoreceptor, a developer for developing an image, and a charging device which charges the photoreceptor, wherein the photoreceptor comprises:

• a photogenerating layer;
• (1) a first charge transport layer formed from a mixture comprising a charge transport component and a resin binder;
• and thereover and in contact with the charge transport layer,
• (2) a second charge transport layer formed from a mixture comprising N,N′-diphenyl-N,N′-bis(alkylphenyl)-1,1-biphenyl-4,4′-diamine, a resin binder and a hindered phenol comprising tetrakis [methylene(3,5-di-tert-butyl-4-hydroxy hydrocinnamate)]methane or 2,6-di-tert-butyl-4-methylphenol dissolved in a solvent comprised of tetrahydrofuran and toluene,
• wherein said second charge transport layer binder comprises a polyphthalate represented by:
• where x represents the number of segments, and n is the degree of polymerization.
