摘要： A non-pneumatic tire is provided including an attachment body (11) attached to an axle, a ring member (14) including an inner tubular body (12) mounted onto the attachment body (11) and an outer tubular body (13) configured to surround the inner tubular body (12) from the outside in a tire radial direction, and a plurality of connecting members (15) disposed between the inner tubular body (12) and the outer tubular body (13) in a tire circumferential direction and configured to connect the tubular bodies (12) and (13) to each other, wherein at least a portion of the ring member (14) and the plurality of connecting members (15) are integrally formed of a synthetic resin material having a breaking elongation of 8.0% or more obtained by a measurement method (23 °C) pursuant to JIS K7161 and a Charpy impact value of 9.4 kJ/m 2 or more obtained by a 23 °C Charpy impact test pursuant of ISO 179-1.

摘要： A cylindrical base for a photosensitive drum composed of a conductive resin composition containing a resin base material and a conductive material mainly containing carbon black, on which base a solvent-using photosensitive layer is directly formed, is characterized in that the resin base material mainly contains a mixed rein wherein (A) a polyester resin and (B) a polycarbonate resin is blended at a ratio (mass ratio) of (A)/(B) = 50/50-90/10. The base for a photosensitive drum is excellent in chemical resistance, formability, dimensional accuracy, and adhesion to the photosensitive layer, while being excellent in dimensional stability. A photosensitive drum using such a base exhibits good printing performance and excellent durability.
