The invention relates to a transfer mechanism for transferring an image on a photosensitive drum ( 4 ) onto an image forming member ( 2 ), and the transfer mechanism is provided with a mechanism ( 28 - 2, 40 to 47 ) for changing the curvature of the print medium ( 2 ) bent by the transfer guides ( 10 ) in order to make the transfer performance of print mediums having different stiffness uniform, in addition to an approach/retraction mechanism ( 28 - 1, 50 to 56 ) of the transfer guides ( 10 ). Since the amount of bite of the print medium to the image forming member can be changed by changing the curvature according to the type of a print medium, a uniform transfer press force can be maintained without the occurrence of transfer displacement, thereby print quality can be improved in various types of print mediums.
