...image area (image forming area), b...non-image area, C...charged area. Amendment April 25, 1980 The scope of claims for utility model registration is amended as follows. O Utility Model Registration Claims (1) An image forming apparatus that forms an image by being equipped with means for developing a charge pattern formed in an image forming area of an image carrier, wherein the developing means faces the image carrier. A developer carrier is arranged to transport the developer and cause the developer to adhere to the charge pattern formed in the image forming area, and a developer carrier is arranged in pressure contact with the developer carrier. an elastic body for forming a developer layer, and a width of the elastic body for forming a developer layer in pressure contact with the image carrier is wider than the width of the image formation. . (2) Utility model registration claim 1, characterized in that the developing means conveys a developer to the image carrier in which charges are formed outside the image forming area, and develops the charge pattern. The image forming apparatus described in .

Claims

[Scope of utility model registration request]

(1) In an image forming apparatus that forms an image by having means for developing a charge pattern formed in an image forming area of an image carrier, the developing means is disposed opposite to the image carrier and moves relative to the image carrier. A developer carrier that transports the developer and causes the developer to adhere to the charge pattern formed in the image forming area; and a developer that is placed in pressure contact with the developer carrier and forms a developer layer on the developer carrier. an elastic body for forming a developer layer, and a width of the elastic body for forming a developer layer in pressure contact with the image carrier is wider than the width of the image formation.

(2) Utility model registration claim 1, characterized in that the developing means conveys a developer to the image carrier in which charges are formed outside the image forming area, and develops the charge pattern. The image forming apparatus described in .
