    Abstract: An image forming apparatus having an insulated member disposed adjacent to a photosensitive member, a scanner exposing an image on the photosensitive member in a direction perpendicular to the direction of movement of the insulated member while voltage is applied between the photosensitive member and the insulated member so as to provide a charge on the insulated member surface corresponding to the optical exposure image. The exposure position exposed by the scanner is changed in the direction of movement of the image-bearing member for each scan.

    Abstract: A thermoplastic resin is stabilized by incorporating therein a dinitrodiamine compound represented by the formula of ##STR1## wherein X is a divalent aliphatic, alicyclic or aromatic group which may contain halogen or oxygen in the group, R.sup.1 is hydrogen or an aliphatic, alicyclic or aromatic group, provided that two nitrogen atoms linking through X may further link through R.sup.1 when both X and R.sup.1 are the aliphatic groups, and R.sup.2 and R.sup.3 independently of one another are each hydrogen or an alkyl of 1 to 12 carbon atoms, provided that R.sup.2 and R.sup.3 may conjointly form a ring. The composition thus blended is improved in thermal processing stability. Further, a modified polyolefin resin is improved in mechanical properties, particularly in impact strength, by the incorporation of the dinitrodiamine compound.

    Abstract: A monocomponent developing device for use in the electrophotographic image forming apparatus, which comprises a developing roller rotatably supported so as to confront a rotatably supported photoreceptor, a toner supply means for supplying toner onto the developing roller, a regulating member held in contact with a surface of the developing roller and operable to triboelectrically charge the toner, supplied onto the surface of the photoreceptor, while regulating the amount of the toner, and a coating film formed on at least a portion of a surface of the regulating member which is held in contact with the developing roller. The coating film has the same polarity in triboelectric series as that of the toner and is abradable after repetition of developing with a surface of the regulating member consequently exposed.
