摘要： A developing apparatus having a developer containing portion including an opening portion for supplying a developer to a developer bearing member, a sheet member for unsealably sealing the opening portion, and a partition wall for partitioning a space of a developer containing portion into a first space and a second space more remote from the developer bearing member than the first space. The partition wall has an angle of 30 degrees or less with respect to a surface on which the sheet member is supported, and has an angle of 40 degrees or more with respect to a horizontal plane when the developing apparatus is attached to a main body of an image forming apparatus. A first carrying and a second carrying member are disposed in the first space and the second space respectively to carry the developer to the opening portion. Before the sheet member is unsealed, the second carrying member is stopped so that a tip end portion of the second carrying member in a rotation radius direction thereof comes close to a tip end portion of the partition wall, and the first carrying member is stopped so that a rotation phase deviates from a stop position of the second carrying member on an upstream side of the rotating direction by an angle of 75 degrees and 105 degrees.
