A toner cartridge for an image forming apparatus including a case body having a tubular portion, first and second end walls, and first and second positioning members. The first positioning member radially protrudes from the first end wall and has a flat end face. The first positioning member, which is used for positioning the toner cartridge at the start of loading the toner cartridge into the image forming apparatus, is aligned with a first guide in the image forming apparatus at the start of loading the toner cartridge. The second positioning member, which radially protrudes from the second end wall of the cartridge and has a flat end face, is angularly shifted from the first positioning member. After the first positioning member is aligned with the guide, the cartridge is rotated to align the second positioning member with a second guide in said image forming apparatus.
