<P>PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of realizing high image quality and high speed processing by accurately transmitting driving to a fixing roller, preventing the occurrence of noise and improving durability. <P>SOLUTION: In the image forming apparatus having a fixing driving device for a fixing unit which can be installed into or taken out of an image forming apparatus main body where the distance between a transfer part and a fixing nip part is shorter than the length of transfer material, a flywheel is attached to the driving shaft of a driving side coupling gear meshed with a fixing roller gear inserted to and fit coaxially with the fixing roller, and the driving shaft is rocked together with the flywheel in a thrust direction through a slide mechanism so as to realize the meshing of the driving coupling gear with the fixing roller gear and the release of the meshing. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
