Provided is a tire assembly includes a tire, a power generating body disposed inside the tire, and an electronic device that receives supply of power that is output from the power generating body. The power generating body includes a first insulating film, a second insulating film, a first electrode, and a second electrode. The first insulating film has a first surface. The second insulating film has a second surface. The first and second electrodes have conductivity. The power generating body is configured such that a true area of contact between the first surface and the second surface changes according to deformation of the tire.

A conductive layer of a conductive member for an image-forming apparatus is composed of a conductive polymer composition containing an ionic-conductive addition salt. The conductive polymer composition has a continuous phase and one or more uncontinuous phases including at least one first uncontinuous phase. The continuous phase and the uncontinuous phase form a sea-island structure. A salt capable of dissociating into cations and anions is unevenly distributed to the first uncontinuous phase. A polymer composing the first uncontinuous phase has a higher degree of affinity for the salt capable of dissociating into cations and anions than a polymer composing the continuous phase to prevent the salt (or the cations, the anions) from shifting out of the first uncontinuous phase or out of the polymer composition. The conductive polymer composition can contain melamine cyanurate so that it is flame-retardant.

An offset printing method is suitable for high-precision printing. Errors caused by the relative movement between a blanket cylinder 4 and a form plate 10 and the rotation of the blanket cylinder 4 on its axis which are produced in a step of transferring an ink image to the blanket cylinder 4 from the form plate 10, are reproduced in the relative movement between the blanket cylinder 4 and a surface to be printed on 11 and the rotation of the blanket cylinder 4 on its axis in a step for printing the ink image on the surface to be printed on 11 from the blanket cylinder 4. The dimensional errors produced in the ink image transferred to the surface 12 of the blanket cylinder 14 of the offset printing methods are cancelled when transferring the ink image from the surface of the blanket cylinder 4 to the surface to be printed on.
