    摘要： An apparatus including a development agent carrying member, a toner container having an opening, an initial development agent container, a flexible member, and a stopper. The flexible member rotates to cyclically transfer toner to the carrying member via the opening. The stopper locates the flexible member at a closed position where the opening is closed. The flexible member is initially located at the closed position and releases the opening when the development agent is present on a surface of the carrying member facing the opening. A method of image forming is provided that includes sealing the opening by engaging the flexible member with the stopper, filling the toner container, supplying a development agent to the carrying member at a surface of the development agent facing the opening, and releasing the opening to start supplying the toner to the carrying member through the opening by rotation of the flexible member.

    摘要： A developing apparatus for an image forming apparatus forms an electrostatic latent image corresponding to an image information signal on an image bearing member. The developing apparatus includes a developer carrying member which bears and conveys a two-component developer containing a non-magnetic toner and a magnetic carrier for forming a toner image by developing the electrostatic latent image formed on the image bearing member. Convexities and concavities are formed on a surface of the developer carrying member. An average peak-to-peak spacing (Sm) of the convexities and concavities is set at ⅓ to 6 times of a weight-average particle diameter of the magnetic carrier (D) (D/3≦Sm≦6*D). An average roughness at ten points (Rz) on the surface of the developer carrying member is set at {fraction (1/10)} to ½ times of the weight-average particle diameter of the magnetic carrier. A number of concavities which are 1 &mgr;m to 10 &mgr;m wide and 0.2 &mgr;m or more deep is smaller than 10 within a spacing of 100 &mgr;m in a surface profile of the developer carrying member. The surface of the developer carrying member is prepared by blasting the surface with definite spherical particles having a weight-average diameter d and a weight-average particle diameter D of the magnetic carrier, according to the following relation: D≦d≦10D.

    摘要： A developing apparatus in which a developer is prevented from attaching to a developer electrifying member. The developing apparatus has a developer carrying body, a regulating member, and a developer carrying member, wherein during a period when developing action is not conducted by the developer carrying body and residual developer is being cleaned, there is a first period during which a first electric field is formed in a direction in which the developer normally charged moves from the developer carrying body to the developer charging member and after the first period there is a second period during which a second electric field is formed in a direction in which the developer normally charged moves from the developer charging member to the developer carrying body.

    摘要： A developing apparatus and a method for assembling the apparatus is capable of uniformalizing a thickness of a developer carried on a developer carrying body, thereby preventing a nonuniform optical density of an image from being produced. The developing apparatus includes a developing frame, a developer carrying body, and a regulating member, wherein the regulating member includes an elastic blade to be brought into contact with the developer and a supporting member for supporting the elastic blade. The supporting member is supported by the developing frame. The elastic blade is coupled with the supporting member by welding.
