摘要： An image forming apparatus includes an image forming portion (6) including a photosensitive member (7) and a developing portion (9), a sheet accommodating portion (2), a sheet feeding portion (3), and a first frame (50). The first frame includes an upper space supporting the image forming portion, and a lower space under the upper space. A second frame (51) is mountable to a lower portion of said first frame. The accommodating portion and the feeding portion are replaceable with a supply container (13) containing toner to be supplied to a developing portion of the image forming portion, in which the second frame supports the accommodating portion and the feeding portion.
