Abstract:
1. A developing apparatus used in an image forming apparatus, comprising: a developer carrying member configured to carry a developer; and a control member configured to control an amount of a developer carried on the developer carrying member, wherein the control member is manufactured by cutting a supporting member covered with a covering member in a cutting direction intersecting a surface of the supporting member to be a predetermined length in the longitudinal direction thereof, the control member has a free end, the covering member is provided near the free end of the control member and covers a part of an opposed surface facing the developer carrying member, a part of a non-opposed surface located opposite to the opposed surface and an end surface located at the free end, the opposed surface of the supporting member is a surface located at an upstream side, in the cutting direction, of the supporting member and the covering member provided on the opposed surface comes into contact with the developer carrying member, in a cutting surface formed by cutting the supporting member, an upstream side in the cutting direction of the cutting surface is covered with the covering member extending from the opposed surface to downstream in the cutting direction, a downstream side in the cutting direction of the cutting surface is exposed from the covering member, and the covering member provided on the non-opposed surface protrudes toward downstream in the cutting direction at a longitudinal end of the control member.
