A developing apparatus includes a rotary shaft member, a sheet member including a first developer conveying portion, an internal edge of which is held by the rotary shaft member, and which conveys developer in a first direction along a rotary shaft of the rotary shaft member, and a second developer conveying portion which conveys the developer in a second direction opposite to the first direction along the rotary shaft. The second developer conveying portion has an internal edge held by the rotary shaft member, and the rotary shaft member is radially disposed between the internal edges of the first and second developer conveying portions. In addition, a reinforcing unit reinforces the sheet member so as to have different degrees of reinforcement with respect to each of the first and second developer conveying portions.
