摘要： An image forming apparatus of the type which develops a latent image on an image carrier with toner stored in a developing unit and transferring the resulting toner image to a recording medium. The developing unit includes a developer carrier which contacts the image carrier at least at two spaced apart points with a gap being formed between the at least two points of contact. A moving mechanism will move opposite ends of the developer carrier independent distances relative to one another so as to eliminate the gap and establish full contact between the image carrier surface and developer carrier surface.

摘要： A powder container is for use with an image forming apparatus, and the image forming apparatus includes a driving protrusion that is rotatable and that protrudes toward an upstream side in an insertion direction in which the powder container is inserted. The powder container includes a container body to store powder, a cap attached to the container body, and a transmitted structure provided on the cap to contact the driving protrusion. The transmitted structure extends outward from an outer circumference of the powder container. The cap is rotatable relative to the container body in a predetermined angular range. The rotation of the cap relative to the container body is restricted so that the container body rotates along with the rotation of the cap when the rotation of the cap exceeds the predetermined angular range.
