Amendment October 30, 2002 The scope of claims for utility model registration is amended as follows.

[Claims for Utility Model Registration] (1) (a) An electrostatic latent image carrier; (b) A developing object that is partially in close contact with the electrostatic latent image carrier; (c) The electrostatic latent image carrier. (d) a means for forming an electrostatic latent image on the surface of the image carrier; (e) a developing device that forms a toner image corresponding to the toner image on the object to be developed, and (e) a pair of rolls disposed so as to be able to approach and separate, and in contact with the object to be developed and the final recording support. (f) a means for collecting the toner on the object to be developed into a developing device; and (g) a jam for detecting the occurrence of a jam on the final recording support. (h) means for bringing the transfer/fixing means into a non-contact state when the occurrence of a jam is detected by the jam detecting means, and when the final recording support becomes defective in conveyance; A recording apparatus characterized by conveying toner on an object to be developed to a developing device, removing the toner from the object to be developed, and collecting the toner in the developing device . (2) (a) an electrostatic latent image carrier; (b) a developing object that is partially in close contact with the electrostatic latent image carrier; and (c) an electrostatic latent image carrier on the surface of the electrostatic latent image carrier. (d) a means for forming a latent image; (d) a means for forming a toner image corresponding to the electrostatic latent image; (e) a transfer/fixing means that is constituted by a pair of rolls and performs transfer and fixing at the same time by overlapping the development object and the final recording support; (f) upper (g) a jam detecting means for detecting the occurrence of a jam on the final recording support; (h) detecting the occurrence of a jam by the jam detecting means; It has means for conveying the object to be developed in the opposite direction when the final recording support is jammed, and the means for conveying the object to be developed in the opposite direction when the final recording support is jammed, removes the toner on the object and returns it to the developing device. A recording device characterized by being collected .
