    Abstract: An objective is to provide an image forming method and an image forming apparatus exhibiting neither failure in lack of line image nor image defect in halftone images, together with extremely high image quality and longer lifetime. Disclosed is an image forming method possessing the steps of evenly charging an organic photoreceptor; conducting a light exposure process; conducting a developing process to visualize the electrostatic latent image formed on the organic photoreceptor to form a toner image; transferring the toner image into a transfer medium; and conducting a cleaning process to remove a residual toner from the organic photoreceptor, the method further comprising the step of replenishing a developing device with a developer comprising toner and carrier, wherein the organic photoreceptor comprises a surface protective layer containing a filler, and the carrier is mixed with the toner, after attaching a lubricant onto a carrier particle in advance.

    Abstract: To provide a process for producing an electrophotographic photosensitive member that can not easily cause any fog due to an increase in dark attenuation, a conductive layer is formed with use of a coating liquid for conductive layer prepared with use of a solvent, a binder material and metal oxide particles. The metal oxide particles (P) and binder material (B) in the coating liquid for conductive layer are in a mass ratio (P/B) of from 1.5/1.0 to 3.5/1.0. The metal oxide particle is a titanium oxide particle coated with tin oxide doped with phosphorus or tungsten. Where powder resistivity of the metal oxide particle is represented by x (Omega·cm) and powder resistivity of the titanium oxide particle as a core particle constituting the metal oxide particle is represented by y (Omega·cm), the y and the x satisfy the following relations (i) and (ii): 5.0×107@y@5.0×109(i) 1.0×102@y/x@1.0×106(ii).

    Abstract: PROBLEM TO BE SOLVED: To provide a process for easily removing coating layers disposed over a substrate of an electrophotographic photoreceptor without damaging the substrate.SOLUTION: The removal process for a photoreceptor coating by use of a stripping solution comprises separating a plurality of coating layers from a substrate of an electrophotographic photoreceptor, wherein the plurality of coating layers are disposed over the substrate. The method comprises: soaking the electrophotographic photoreceptor in a stripping solution containing nitric acid, hydrofluoric acid, hydrochloric acid, phosphoric acid, sulfuric acid, oxalic acid, acetic acid, carbonic acid, lactic acid, formic acid, malic acid, phthalic acid, or mixtures thereof; degrading the plurality of coating layers with the stripping solution; and separating the plurality of coating layers from the substrate without degrading or corroding any portion of the substrate.
