Abstract:
An image forming apparatus comprising:an image carrier for forming a toner image thereon;an intermediate transfer body to which said toner image is transferred from said image carrier in a first toner image transfer operation;a transfer medium,a transferring means for transferring said toner image from said intermediate transfer body to said transfer medium in a second toner image transfer operation;a fixing means for fixing said toner image on said transfer medium;fixing speed switching means for selectively causing the transfer medium to move through the fixing means at one of a first speed that matches a peripheral speed of the image carrier and a second speed lower than said first speed, said first speed and said second speed corresponding to respective speeds for fixing said toner image on different varieties of said transfer medium; andperipheral speed switching means for switching a peripheral speed of the intermediate transfer body from a peripheral speed matching the peripheral speed of the image carrier necessary for toner image formation during said first toner image transfer operation to a peripheral speed matching said second speed when said fixing speed switching means causes the transfer medium to move through said fixing means as said second speed.
