Abstract:
1. An image forming apparatus comprising: an image forming unit configured to form toner images on transfer materials; a fixing unit configured to include a timing adjusting unit disposed upstream of the image forming unit in a conveying direction of the transfer materials and configured to adjust the timing of supplying the transfer materials to the fixing nip; a temperature detecting unit configured to detect a temperature of a predetermined section of the heat rotating body; a power supply unit configured to start or continue supplying electric power to the heater unit of the heating rotating body; and a timing control unit configured to control the timing adjusting unit, wherein, in the event that the power supply unit starts supplying electric power to the heater unit of the heating rotating body, the timing control unit is configured to select a first mode or a second mode in accordance with whether the number of transfer materials to be printed exceeds a predetermined number, the first mode for controlling the timing adjusting unit to supply a first transfer material when the temperature of the predetermined section of the heating rotating body detected by the temperature detecting unit exceeds a first temperature, the second mode for controlling the timing adjusting unit to supply the first transfer material when the temperature of the predetermined section of the heating rotating body detected by the temperature detecting unit exceeds a second temperature different from the first temperature.
