Abstract
A drum member includes: a substantially cylindrical drum body having a hollow part extending in an axial direction; a sheet member wound on the drum body; an adjusting mechanism configured to adjust tension in the sheet member, the adjusting mechanism including a moving member that holds an end of the sheet member in a circumferential direction and moves in a depth direction of the hollow part, and a fixing member that fixes the moving member to the drum body; and one or more positioning members that position the moving member such that the moving member does not move in the circumferential direction of the drum body when the moving member is fixed with the fixing member.
