摘要： An electrophotographic toner showing a good fixability onto recording paper is constituted by at least a binder resin and a colorant, the binder resin comprising a resin component having a polar group, the binder resin having a molecular weight distribution according to gel permeation chromatography including a peak in a molecular weight region of 5x10³ - 5x10⁴. The toner is used to develop an electrostatic image formed on a electrophotographic photosensitive member including at least an electroconductive support, a charge generation layer and a charge transport layer, and the resultant toner image is transferred onto a recording medium without difficulties such as occurrence of cracks on the photosensitive member or inferior transferability by using a photosensitive member having a surface layer containing a transition metal atom at 0.1 - 10 ppm. The surface of the photosensitive member may preferably show a fluorine atom/carbon atom (F/C) ratio or/and a silicon atom/carbon atom (Si/C) ratio, respectively, of 0.03 - 1.0 as measured by X-ray photoelectron spectroscopy.

摘要： An electrostatographic imaging member comprising a photoconductive layer which comprises an organic resin binder and photoconductive particles. The photoconductive particles comprise selenium coated with thin layer of a reaction product of a hydrolyzed aminosilane. This electrostatographic imaging member may be prepared by forming a mixture of an organic resin binder, the photoconductive particles coated with a thin layer of a reaction product of a hydrolyzed aminosilane, and a solvent for the binder to form a uniform dispersion, forming the dispersion into a uniform layer, and drying the uniform layer to form a photoconductive layer.

摘要： An electrophotographic recording material comprising a photoconductive layer incorporating photoconductive zinc oxide in the presence of a compound within the scope of the following general formula:
wherein:
R represents (1) an unsubstituted aliphatic hydrocarbon group containing at least 5 carbon atoms or (2) an aliphatic hydrocarbon group substituted with a -COOQ group wherein Q is an organometallic group or an aliphatic hydrocarbon group, containing at least 5 carbon atoms, or (3) an aliphatic hydrocarbon group substituted with a -COOH group and containing at least two methylene groups between the -COOH group and the -SH group, and said gen- erai formula including the modification wherein the hydrogen atom of the -SH group is substituted to form an organometal mercaptide.
The above compound improves the charge retention of the photoconductive layer, i.e. lowers its dark-decay, under conditions of high relative humidity.-
