Patent ID: 8478172

Claim:
A transport member for a powder transport comprising: a revolving shaft; plural transport parts including at least one transport part that extends in a helical shape relative to an axial direction of the revolving shaft in a nonoperating status, the at least one transport part including one end part with a free end and an other end part at an opposite side of the one end part, and transporting a powder at the time of revolution of the revolving shaft; a support part that supports the other end part of the at least one transport part by being arranged with the revolving shaft; and a reinforcement part that is arranged adjacent to the support and connects between an adjacent portion of the other end part of the at least one transport part and the revolving shaft, wherein the at least on transport part is not supported by a second support part, or the at least one transport part is supported by the second support part that is arranged at a phase angle between the support part and the second support part of more than 0 degrees and less than 90 degrees, with respect to a perpendicular cross-section of an axial direction of the revolving shaft, wherein a central angle of a helix arc, which is between the free end and the other end part of the at least one transport part, is more than 90 degrees with respect to a perpendicular cross-section of an axial direction of the revolving shaft.
