  • Publication number: 20120028175
    Abstract: A method for forming an image at least comprising steps of forming an electrostatic latent image by exposing an electrophotographic photoreceptor, forming a foil transferring face by supplying a toner onto the electrophotographic photoreceptor having the electrostatic latent image, transferring the foil transferring face formed on the electrophotographic photoreceptor to a base substance, fixing the foil transferring face transferred on the base substance, supplying a transfer foil to the base substance fixed with the foil transferring face, adhering the transfer foil onto the foil transferring face by heating under a condition of contacting the transfer foil with the foil transferring face; and removing the transfer foil from the base substance while leaving the foil adhered onto the foil transferring face, wherein the toner comprises a binder resin having a softening temperature in the range of from not less than 105° C. to not more than 140° C.

  • Publication number: 20100151375
    Abstract: An objective is to provide a toner product with which the difference between the water content of a toner in a toner container and the water content of another toner present in an image forming apparatus is minimized, and a sharp charging amount distribution can be obtained to form high-quality images; and also to provide an image forming method thereof. Also disclosed is a toner product in which a toner is stored in a toner container, wherein the toner possesses a toner particle having an amount of a carboxyl group present on a surface of the toner particle, being 1.0×10?7-2.5×10?5 mol/g, and the toner container is made of a resin containing polyethylene terephthalate, the amount of the carboxyl group determined via titration employing a strongly basic solution as a titration reagent after dispersing the toner in water.
