Abstract: A gummed paper comprises a first substrate having an uncovered region on an upper surface thereof; and a second substrate, in which in a thickness direction, a projection of the second substrate partially covers a projection of the first substrate, a dyne value of an upper surface of the second substrate is greater than or equal to 40 dyn/cm, and a dyne value of the uncovered region is less than the dyne value of the upper surface of the second substrate.

Abstract: Disclosed is a production apparatus of a wired member, including: a mask forming unit that forms a mask on a transfer substrate by using a toner in accordance with an electrophotographic method so as to be transferable to a member to be wired, the mask corresponding to a wiring pattern to be formed on the member to be wired; a mask transferring unit that transfers the mask formed on the transfer substrate by the toner to the member to be wired; a conductive film forming unit that supplies a conductive material onto the mask-transferred side of the member to be wired to form a film of the conductive material thereon; and a mask removing unit that removes the mask from the member to be wired on which the film of the conductive material has been formed.

Abstract: A chemical toner composition that includes at least one curable amorphous resin and at least one sublimation colorant.

Abstract: A via hole forming method and a multilayered board manufacturing method improve manufacturing yield by reducing the required processes. The via hole forming method includes a first step of forming a toner image by attaching toner particles, containing a conductive material and having a protruding portion, onto the surface of a first photosensitive member so that the protruding portion is directed to the outside; and a second step of opposing the surface of the first photosensitive member to one principal surface of a green sheet containing an insulating material and transferring the toner image to the one principal surface of the green sheet so that the protruding portions of the toner particles protrude into the green sheet so as to reach the other principal surface of the green sheet and the toner particles are buried in the green sheet. The via holes are formed using an electrophotographic printing method.
