Claim:
1. An image forming apparatus, comprising: an image forming section configured to form a toner image on a medium; a fixing section configured to include a heating section and a pressurization section, and to enable the medium on which the toner image is formed to pass a portion between the heating section and the pressurization section to fix the toner image on the medium; a switching section configured to switch a heating mode between the first heating mode and the second heating mode, wherein under the first heating mode, the heating section and the pressurization section respectively are controlled at a first temperature and a second temperature to carry out a fixing processing, and under the second heating mode, the heating section is controlled at a temperature higher than the first temperature and the pressurization section is controlled at a temperature lower than the second temperature to carry out a fixing processing; a control section configured to determine whether or not a sleep time t is longer than a predetermined time ts and to determine whether or not a temperature Th of a heat roller is lower than a given temperature Tc; and wherein the control section is further configured to switch the heating mode to the second heating mode through the switching section in a case in which the temperature of the heating section is lower than a predetermined temperature, and to switch the heating mode to the first heating mode through the switching section in a case in which the temperature of the heating section is equal to or higher than the predetermined temperature.
