An electrophotographic image forming method using an electrophotographic photoconductor includes the steps of charging the photoconductor to a predetermined polarity using a charger which may be disposed in contact with the photoconductor, exposing the charged photoconductor to light images to form latent electrostatic images thereon, developing the latent electrostatic images into visible images with a toner, and transferring the visible toner images formed on the photoconductor to an image receiving member using an image transfer charger which may be disposed in contact with the photoconductor, with the photoconductor comprising a surface top layer which contains a compound of formula (I): ##STR1## wherein R.sup.1 is a lower alkyl group; R.sup.2 and R.sup.3 are each independently methylene group which may have a substituent or ethylene group which may have a substituent; Ar.sup.1 and Ar.sup.2 are each an aryl group which may have a substituent; and l is an integer of 0 to 4, and m and n are each an integer of 0 to 2 provided that m+n.gtoreq.2 and l+m+n.ltoreq.6.
