What is claimed is: 1. A toner supply container detachably mountable to an image forming apparatus, said toner supply container comprising: a container body for containing toner, said container body being provided with an opening portion for permitting discharge of the toner therefrom; and a feeding member, provided in said container body, for feeding the toner in said container body toward said opening portion, wherein said feeding member includes a rotatable plate-like member extending in a longitudinal direction of said container body, said plate-like member including a projection, extending at an incline relative to a rotational axis of said plate-like member to guide the toner toward said opening portion with rotation of said plate-like member and a through-hole effective to allow the toner on said plate-like member to fall with rotation of said plate-like member, thus stirring the toner. 2. A toner supply container according to claim 1, wherein a plurality of such projections are provided at longitudinally different positions on one side of said plate-like member. 3. A toner supply container according to claim 1, wherein a plurality of such projections are provided at longitudinally different positions on both sides of said plate-like member. 4. A toner supply container according to claim 3, wherein said plurality of projections are provided on both sides of said plate-like member so as to effect a toner discharging action twice for one full rotation of said plate-like member. 5. A toner supply container according to any one of claims 2, 3, and 4, wherein one of said plurality of projections is substantially close to or contiguous with said opening portion. 6. A toner supply container according to any one of claims 2, 3, and 4, wherein said plurality of such projections are provided so as to be partly overlapped with respect to a longitudinal direction of said plate-like member. 7. A toner supply container according to any one of claims 2, 3, and 4, wherein said plurality of said projections are provided, and said through-hole is provided between each of adjacent ones of said projections. 8. A toner supply container according to any one of claims 2, 3, and 4, further comprising a hollow extension extending from said opening portion, said extension having an opening at a free end thereof to permit discharge of the toner. 9. A toner supply container detachably mountable to an image forming apparatus, the toner supply container comprising: a rotatable container body for containing toner, said container body being provided with an opening portion for permitting discharge of the toner therefrom; and a feeding member, provided in said container body, for feeding the toner in said container body toward said opening portion by integral rotation thereof with said container body, wherein said feeding member includes a rotatable plate-like member extending in a longitudinal direction of said container body, said plate-like member including a projection, extending at an incline relative to a rotational axis of said plate-like member to guide the toner toward said opening portion with rotation of said plate-like member and a through-hole effective to allow the toner on said plate-like member to fall with rotation of said plate-like member, thus stirring the toner. 10. A toner supply container according to claim 9, wherein a plurality of such projections are provided at longitudinally different positions on one side of said plate-like member. 11. A toner supply container according to claim 9, wherein a plurality of such projections are provided at longitudinally different positions on both sides of said plate-like member. 12. A toner supply container according to claim 11, wherein said plurality of projections are provided on both sides of said plate-like member so as to effect toner discharging action twice for one full rotation of said plate-like member. 13. A toner supply container according to any one of claims 10 through 12, wherein one of said plurality of projections is substantially close to or contiguous with said opening portion. 14. A toner supply container according to any one claims 10 through 12, wherein said plurality of projections are provided so as to be partly overlapped with respect to a longitudinal direction of said plate-like member. 15. A toner supply container according to any one of claims 10 through 12, wherein said plurality of projections are provided, and said through-hole is provided between each of adjacent ones of said plurality of projections. 16. A toner supply container according to claim 13, further comprising a hollow extension from said opening portion, said extension having an opening at a free end thereof to permit discharge of the toner. 17. A toner supply container according to claim 9, wherein the container is substantially cylindrical. 18. A toner supply container according to claim 9, wherein said plate-like member is disposed so as to be close to or in contact with an inside peripheral surface of said container body. 19. A toner supply container according to claim 9, wherein said plate-like member extends substantially along a full length of said container body. 20. A toner supply container according to claim 9, wherein said plate-like member diametrically divides an inside of said container body into two substantially equal parts.
