Abstract:
1. An image forming apparatus comprising: an image forming section configured to form an image on a recording medium; a fixing section which includes a heat roller internally provided with a heater, and a pressure roller and is configured to fix a toner image transferred to the recording medium by the formation image done by the image forming section; a temperature detecting section configured to detect the temperature of an end region of the heat roller in a direction of a rotary axis of the heat roller; a control section configured to control the operation of the heater based on the temperature detected by using the temperature detecting section; and a post-drive time calculating section configured to calculate a post-drive time required for a post-drive to be performed by the fixing section after the image forming section successively forms images on recording media and the fixing section successively fixes the images on the recording media, the post-drive time calculating section calculating the post-drive time depending upon the sizes of the recording media used in the successive formation of the images and through a subtraction using a correction factor set according to a condition of conveyance of the recording media to the fixing section after the successive formation of the images, wherein the control section causes the fixing section to perform the post-drive for the post-drive time calculated by the post-drive time calculating section, and wherein the post-drive time calculating section applies, as an element constituting the condition of conveyance, the case where a predetermined operation causing extension of the distance between the recording media being successively conveyed to the fixing section is performed.
