A Few Selected Research Topics of Research Center of MEMS Space Telescope

A developer feeding member feeds a developer. The developer feeding member includes an elastic sheet for feeding the developer, and a rigid supporting portion for supporting this elastic sheet. In the developer feeding member, this developer feeding member is rotatable as the supporting portion is centered as a rotation center, and a flexural rigidity of a free end of the elastic sheet is smaller than that of a portion of the elastic sheet, which is located in the vicinity of this supporting portion.
