A developer cartridge capable of being fitted to the toner replenishing opening of a developer storage hopper has a sealing member for sealing the toner therein that is bonded to the rim of its replenishing opening to be opposed to the opening of the developer storage hopper. The bottom face of this developer cartridge which constitutes the bottom for supporting the toner stored therein is inclined upwards in the stripping direction of the sealing member, whereby the supplied amount of the toner at the stripping start of the sealing member is regulated when the sealing member is stripped so that the toner can be uniformly supplied across the full length of the developer storage hopper with respect to the stripping direction of the sealing member.

[ What is claimed is:] [1.]1. A developer cartridge for holding a developer supplied to a developer storage hopper, comprising:a container box having an open face which is fitted to a replenishing opening of the developer storage hopper, said container box being substantially filled with the developer; anda sealing member removably bonded to a rim of the opening of the container box to seal the developer in the container box, wherein the container box is detachably set to the developer storage hopper with the sealing member opposed to the replenishing opening of the developer storage hopper,wherein the container box is shaped so that the developer is uniformly supplied from the developer cartridge to the developer storage hopper through the replenishing opening from a stripping start area of the sealing member to a stripping end area of the sealing member along the stripping direction,wherein at least a portion of a first end face of said container box adjacent to the stripping start area is substantially parallel to a second end face of said container box adjacent to said stripping end area and opposed to said first end face, andwherein the container box has a first face opposed to the sealing member and inclined in a first direction so that a height thereof is lowest at the stripping start area of the sealing member, wherein said height gradually increases in the stripping direction.
