Abstract
A development device includes a layer thickness regulating blade including a support sheet metal, a blade rubber section, and a side edge seal, the support sheet metal having a first end portion, a second end portion, and a center portion between the first end portion and the second end portion, in an axial direction of a development roller. In a width direction of the support sheet metal, the first end portion of the support sheet metal in the axial direction is shorter than the center portion of the support sheet metal in the axial direction. In the width direction, a distal-end edge of the first end portion of the support sheet metal is closer to a base end portion of the support sheet metal than a distal-end edge of the blade rubber section.
