In zinc-system-plated steel materials, a high-strength quenched formed body, in which the corrosion resistance of after-quenching formed products is equal to or more than that of cold-molded products, and a production process for the same are provided. The high-strength quenched formed body contains a layer, in which Zn is a major component and which is formed of Fe: 30% by mass or less, in an amount of 30 g/m2 or more on the surface of an after-quenching formed-body steel material, and accordingly is good in corrosion resistance. A quenched formed body is produced by quenching a zinc-plated steel material, which includes a zinc-plated layer which contains each of Al and Si having alloying-retarding function and readily-oxidizing function independently or compositely, in an amount of 0.15% by mass or more, after heating it to 800° C. or more and 95° C. or less in an oxidizing atmosphere of oxygen: 0.1% by volume or more.

An image forming method is performed by an image forming apparatus having a head mounting a plurality of writing units that form an image on a recording medium. The writing units are aligned in a sub-scanning direction perpendicular to a main-scanning direction. A part of the image is formed on the recording medium by the writing units, the part of the image forming a line extending in the main-scanning direction. The step of forming a part of the image is repeated while shifting the writing units in the sub-scanning direction by a predetermined amount of shift. The amount of shift of the wiring units is varied so that an amount of misalignment in a connecting portion between the parts of the image on the recording medium is reduced.

A method of producing a composite sheet in which a through hole formed in a predetermined portion of the first ceramic sheet is buried with a different kind of sheet having substantially the same thickness as the first ceramic sheet, such as a resin sheet a metal sheet or a ceramic sheet of a material different from that of the first ceramic sheet. A first method comprises a step of preparing a first ceramic sheet from a ceramic powder, and a different kind of sheet; a step of forming a through hole in a predetermined portion of the first ceramic sheet; a step of laminating the different kind of sheet on the ceramic sheet in which the through hole is formed; and a step of preparing a composite sheet by pressing the portion of the first ceramic sheet where the through hole is formed from the side of the different kind of sheet, such that the first ceramic sheet and the different kind of sheet are integrated together. A second method comprises a step of preparing a first ceramic sheet and a different kind of sheet, and laminating the first ceramic sheet and the different kind of sheet one upon the other; and a step of preparing a composite sheet by pressing a predetermined portion of the laminate from the side of the different kind of sheet, such that the pressed portion of the different kind of sheet is transferred onto the side of the first ceramic sheet to integrate the first ceramic sheet and the different kind of sheet together. A further method is for producing a laminate by laminating the obtained composite sheet on other first ceramic sheet or on other composite sheet.
