ABSTRACT:
An electrophotographic process includes providing an organic photoconductor comprised of a charge generation layer and a charge transport layer containing a poly(alkanedioic acid 2,6-dimethoxyanthracene-9,10-diol ester) resin formed on a conductive substrate, and having a half decay exposure; and eliminating static from the organic photoconductor by illuminating the organic photoconductor with a static elimination light having a wavelength ranging from 520 to 680 nm and with a dose of the static elimination light which ranges from 3 to 10 times the half decay exposure of the organic photoconductor. Preferably, the wavelength of the static elimination light ranges from 550 to 650 nm. An electrophotographic apparatus includes an organic photoconductor comprising a charge generation layer and a charge transport layer containing a poly(alkanedioic acid 2,6-dimethoxyanthracene-9,10-diol ester) resin formed on a conductive substrate, and having a half decay exposure; a static elimination light source providing light having a peak wavelength ranging from 520 to 680 nm, and providing an irradiation dose of the light ranging from 3 to 10 times the half decay exposure of the organic photoconductor; and a controller for correctively controlling developing bias in response to one of (a) temperature and relative humidity in the surroundings of the organic photoconductor or (b) accumulated number of repeated uses of the organic photoconductor; and
