The present invention realizes a fixing device and an image forming apparatus in each of which (i) the amount of power consumption is small and (ii) a wait time from when a command for starting printing is inputted until when printing is started is short. The fixing device of the present invention includes (i) a fixing roller ( 250 ) and a pressure roller ( 251 ) which are provided so as to contact each other, (ii) a thermal heater ( 252 ) for heating the fixing roller ( 250 ), (iii) a thermistor ( 254 ) for detecting the temperature of the fixing roller ( 250 ), and (iv) a heating control section ( 255 ) for controlling a drive start or drive stop of the thermal heater ( 252 ). The heating control section ( 255 ) carries out control of the thermal heater ( 252 ) for a predetermined time, and restarts the control of the thermal heater ( 252 ) based on a difference between (i) the temperature of the fixing roller ( 250 ) when the control of the thermal heater ( 252 ) is stopped and (ii) the temperature of the fixing roller ( 250 ) after a certain time has elapsed since the control of the thermal heater ( 252 ) is stopped. |
