    • There are provided a recording liquid that produces high-quality images having a very high image density and water resistance, and can be discharged continuously and stably; a method for manufacturing such a solution; and a method for recording images by the use of such a solution. The recording liquid for ink printers according to the present invention contains a pigment and at least two kinds of fine resin particles, wherein the dispersion polarity of the pigment is the same as the dispersion polarity of each of the two or more kinds of fine resin particles. The method for manufacturing a recording liquid for ink printers has the step of mixing an aqueous dispersion of a pigment, and an aqueous dispersion of the two or more kinds of fine resin particles each having a polarity the same as the polarity of the aqueous dispersion of the pigment. The method for recording images on a recording medium has the step of discharging droplets of the recording liquid from a recording head, wherein the above recording liquid is used as the recording liquid.

    • An electrophotographic photoreceptor is disclosed, comprising a substrate having thereon a light-reflection preventing layer comprising an anodized aluminum film and a photosensitive layer in this order. And the electrophotographic photoreceptor can be produced by a process comprising subjecting a substrate at least a surface of which comprises aluminum or an aluminum alloy to anodic oxidation in a neutral aqueous solution containing at least one of boric acid, boric acid salt, a phosphoric acid salt, etc. in a concentration of from 1 to 30% by weight or an acidic aqueous solution containing at least one of sulfuric acid, phosphoric acid, oxalic acid, chromic acid, etc. in a concentration of from 1 to 30% by weight to form an anodized aluminum film as a light reflection-preventing layer on the substrate, and then forming a photosensitive layer on said anodized aluminum film. The anodized aluminum film prevents appearance of an interference fringe when the photoreceptor is applied to a laser beam printer.
