ABSTRACT:
A developer layer thickness regulating device for a developing unit improves the sealing effect of a developer by regulating a thickness of a developer layer formed on a developing roller. The device includes a blade having a blade body that is in resilient contact with the developing roller. A bent part is formed on the blade body and extends at a predetermined angle from a developing roller contact part that is in contact with the developing roller, and a recessed part formed on the bent part. A sealing member is in contact with the blade. The sealing member overlaps with the recessed part.
