<P>PROBLEM TO BE SOLVED: To provide a fixing device capable of surely preventing deviation or rubbing on an image which is transferred and fixed on a recording medium even when the kind of the recording medium and the kind of the image are varied while restraining a cost increase associated with the increase of the number of components by optimizing the conveyance state of the recording medium between a transfer part and a fixing means. <P>SOLUTION: The fixing device includes a speed detection means for detecting at least the conveying speed of the recording medium obtained immediately after the recording medium rushes in a fixing nip part, and a speed changing means for changing the conveying speed of the recording medium which passes through the fixing nip part. It is constituted to change the conveyance speed of the recording medium which passes through the fixing nip part by the speed changing means on the basis of the speed of the recording medium obtained immediately after the recording medium rushes in the fixing nip part detected by the speed detection means, and adjusts it to target speed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
