Patent ID: 7945180

Claim:
An image forming apparatus for forming on a recording material an image corresponding to image data, the image forming apparatus comprising: feeding means for feeding a recording material; image forming means for forming a toner image corresponding to image data, and for transferring the toner image onto the recording material; and fixing means for fixing on the recording material the toner image that was transferred by said image forming means, said image forming apparatus, further comprising: control means, when a feeding error of a recording material occurs in the fixing means and then an image corresponding to image data which was formed on the recording material which caused the feeding error of the recording material is re-formed on another recording material, for causing an operation condition which affects a peeling characteristic of the recording material with respect to the fixing means among operation conditions under which said each means works when an image is formed to be changed to an operation condition which improves the peeling characteristic of the recording material with respect to the fixing means than an operation condition used when the feeding error has occurred, the operation condition which affects the peeling characteristic of the recording material being at least two operation conditions among the following operation conditions: an operation condition for changing a width, extending in a recording material feeding direction, of a region on which no image is formed in an end part of the recording material upstream in the recording material feeding direction; an operation condition for changing a printing density of the toner image to be transferred onto recording material; a temperature of said fixing means during forming of the image; and a feeding speed of the recording material; and storing means for storing an order of priorities of the operation condition caused to be different by said control means when the image is re-formed, said control means successively changing the operation condition caused to be different by said control means when the image is re-formed, the operation condition being successively changed one by one every time re-forming is performed, based on the frequency of having performed re-forming and the order of priorities each time re-forming is performed.
