摘要:
An image forming method including forming an image of a toner including a wax on a recording medium; fixing the toner image using by an oil-less fixing device; and then forming an overcoat layer on the fixed toner image. When a portion of the fixed toner image having the heaviest toner weight is subjected to an ATR FT-IR analysis, a peak area ratio Ab/Aa falls in a range of 3.0 to 7.0 or a peak area ratio Ab′/Aa′ falls in a range of 0.004 to 0.014, wherein Aa represents the area of a peak present in a range of 2896 cm−1 to 2943 cm−1, Ab represents the area of a peak present in a range of 2946 cm−1 to 2979 cm−1, Aa′ represents the area of a peak present in a range of 791 cm−1 to 860 cm−1, and Ab′ represents the area of a peak present in a range of 2834 cm−1 to 2862 cm−1.

摘要:
An image forming method including forming a toner image on a transfer medium with a toner comprising a wax having a polar group, and applying a varnish to the toner image. The wax may be a plant wax having an ester group, a wax having a polar group derived from a fatty acid, an oxidized wax, or a mixture thereof. The varnish may include a surfactant, such as a polyoxyethylene glycol, and may be photocurable.

摘要:
A method of evaluating electrophotographic overcoatability of a composition is provided. The method includes measuring a color (C1) of a toner image fixed on a sheet, dropping the composition on the toner image, and removing the composition from the toner image. The method further includes measuring a color (C2) of the toner image from which the composition has been removed, and calculating a color difference between the color (C1) of the toner image and the color (C2) of the toner image on which the composition is dropped and from which the composition is removed thereafter.
