PROBLEM TO BE SOLVED: To provide an image forming apparatus having duplex printing function, configured to properly control conveyance of a sheet according to a temperature.SOLUTION: When an internal temperature sensor 61 arranged inside a frame outputs a signal indicating a temperature higher than an internal threshold temperature and an external temperature sensor 62 arranged outside the frame outputs a signal indicating a temperature higher than an external threshold temperature, a printer 100 conveys a sheet at a first speed to execute printing in a printing section 10 in one-side printing mode, or conveys the sheet at a second speed lower than the first speed to execute printing in the printing section 10 in duplex printing mode.SELECTED DRAWING: Figure 4 |
