Claim:
An image forming apparatus comprising: an image carrier on which an electrostatic latent image is formed; a developer, comprising: a container, containing toner; a first roller, facing the image carrier, and rotated to cause the toner to adhere onto the image carrier to develop the electrostatic latent image as a toner image; a second roller, supplying the toner from the container to the first roller; and a control member, extending in an axial direction of the first roller, and brought into contact with the first roller, wherein a tip end edge of the control member is situated in an upstream side of a contact line that extends in the axial direction so as to include at least one contact point between the control member and the first roller, relative to a rotating direction of the first roller, a distance between the tip end edge and the contact line is not constant relative to the axial direction, and a distance between opposite end portions of the tip end edge in the rotating direction and the contact line is greater than a distance between a center portion between the opposite end portions and the contact line so that the tip end edge has an arcuate shape.
