A method of preparing an organic photoconductor drum having a protective overcoat on its outermost surface is provided. In an example embodiment, a photoconductor drum having an electrically conductive substrate, a charge generation layer, a charge transport layer and an outermost protective overcoat layer is provided. The photoconductor drum is cured using a two-step process. The first curing step applies either ionizing irradiation, such as with an electron beam or by gamma rays or applies non-ionizing irradiation such as ultraviolet light to the photoconductor drum. A mask is sized and placed over the print area of the initially cured photoconductor drum, thereby exposing the outermost edges of the photoconductor drum. The outer edges of the masked photoconductor drum is then exposed to a second curing step using ultraviolet light irradiation.

An improved overcoat layer for an organic photoconductor drum used in an electrophotographic image forming device is provided. The overcoat layer is prepared from a curable composition including a charge transport molecule containing four radical polymerizable hydrophilic functional groups containing an oxygen atom of the general structure shown below: ##STR00001##
wherein R.sub.1 and R.sub.2 contain a spacer group and a radical polymerizable hydrophilic functional group containing an oxygen atom, R.sub.3 and R.sub.4 are a non-radical polymerizable functional group, and R.sub.5 and R.sub.6 contain a spacer group and a radical polymerizable hydrophilic functional group containing an oxygen atom. The curable composition may also contain at least one optional curing agent. This overcoat layer improves wear resistance of the organic photoconductor drum without negatively altering the electrophotographic properties, thus protecting the organic photoconductor drum from damage and extending its service life.

Provided are a recording paper having not only excellent appearance and high adhesion between a substrate and a resin coating but also high adhesion, particularly, high water resistant adhesion to ink or toner in various printing systems and a method for producing the recording paper. The recording paper of the present invention includes: a substrate composed of a thermoplastic resin film; and a resin coating disposed on at least one side of the substrate, wherein the resin coating contains a resin that is a reaction product of a cationic water-soluble polymer and a silane coupling agent, a content of a silane coupling agent component is 15 to 35 mass % based on a cationic water-soluble polymer component in the resin coating, and the resin coating is free from thermoplastic resin particles.

An image forming apparatus executes an image forming operation adequately while reducing a cumbersome work of a user of setting the sheet size. A processor of the image forming apparatus controls an image forming portion to form the image on the sheet even if the sheet size included in an image forming job is inconsistent with the sheet size stored in a storage portion. In such a mode, the processor controls a notification portion so as to give notification when a size detection portion detects one of regular sheet sizes and where the sheet size included in the image forming job is inconsistent with the detected sheet size.

Herein is described a method of applying foil from a foil web to a substrate. The method may comprise: ink-jet printing a UV-curable adhesive onto the substrate in a predetermined image area; subjecting the adhesive to a first curing by exposing the adhesive to UV light in a dosage range of 140-170 mJ/cm.sup.2; passing the substrate and a foil web through a nip where the foil web is pressed against the adhesive; subjecting the adhesive disposed between the substrate and the foil web to a second curing by exposing the adhesive to UV light in a dosage of at least 250 mJ/cm.sup.2; and separating excess foil from the substrate, to leave foil on the predetermined image area. Substrates and UV-curable adhesives are also described.

A method of curing a protective overcoat layer on the outermost portion of an organic photoconductor drum using dual curing process is provided. The first curing step applies either ionizing irradiation, such as with an electron beam or by gamma rays or applies non-ionizing irradiation such as ultraviolet light to the overcoated photoconductor drum. A mask or shield is sized to be placed over the print area of the initially cured photoconductor drum, thereby exposing the outermost edges of the photoconductor drum. The outer edges of the masked photoconductor drum is then exposed to a second curing step using non-ionizing irradiation such as ultraviolet light.
