Claims

What is claimed is:
1. A device to regulate toner within an image forming apparatus comprising: a longitudinal edge that regulates the toner;
a lateral edge that forms a corner with the longitudinal edge; and
a gap positioned within the longitudinal edge and spaced inward from the corner.

2. The device of claim 1 , wherein the gap includes an inner edge, an outer edge and an upper edge.

3. The device of claim 2, wherein the upper edge is located within a contact zone that contacts a developer roller.

4. The device of claim 3, wherein the upper edge is positioned entirely within the contact zone.

5. The device of claim 2, wherein the upper edge is substantially parallel to the longitudinal edge.

6. The device of claim 2, wherein the inner and outer edges are substantially parallel.

7. A device to contact and regulate toner on a developer roll within an image forming apparatus comprising:
an edge that extends beyond a contact area formed with the developer roll;
a regulating section that contacts the developer roller, the regulating section being spaced inward from the first edge; and a gap defined between first and second points along the edge and having a depth to extend into the regulating section.

8. The device of claim 7, wherein the gap comprises three separate sides.

9. The device of claim 7, wherein the gap has at least one arcuate edge.

10. The device of claim 7, further comprising a second gap positioned along the edge and being spaced apart from the gap.

11. The device of claim 7, further comprising a mounted edge opposite from the edge, the mounted edge being mounted to the image forming apparatus.

12. The device of claim 7, wherein a distance defined between a center of the regulating section and the edge is between about 0.6mm and about 1.4mm.

13. The device of claim 12, wherein the regulating section has a length of about 1 mm.

14. A device to regulate toner within an image forming apparatus comprising:
a longitudinal edge;
a regulating section positioned inward from the longitudinal edge; and a gap positioned along the longitudinal edge having an upper edge substantially parallel to the longitudinal edge and extending into the regulating section.

15. The device of claim 14, wherein the gap extends inward from a lateral edge.

16. A device to regulate toner within an image forming apparatus comprising:
a developing roller;

a regulating member having a longitudinal edge and a contact section spaced inward from the longitudinal edge to contact and regulate the toner on the developing roller; and
a gap extending inward from the longitudinal edge and having a regulating edge positioned within the contact section.

17. The device of claim 16, wherein the gap comprises at least two sides.

18. The device of claim 16, wherein the developing roller rotates in a direction into the longitudinal edge of the regulating member.

19. The device of claim 16, wherein the gap has at least one arcuate section.

20. The device of claim 16, further comprising a second gap extending inward from the longitudinal edge and being spaced apart from the gap.
