Abstract:
1. An image forming apparatus comprising: a fixing device including: a temperature detecting member configured to detect the temperature of the heating member; a driving source configured to rotate at least one of the heating member and the backup member; a transmitting mechanism configured to transmit a driving force of the driving source to the at least one of the heating member and the backup member; and a control device configured to control the heat source and the driving source, wherein, after a power is turned on, the control device turns on the heat source before the driving source is driven for the first time and restricts driving of the driving source for a predetermined period, wherein, when at least one of a condition where the temperature detected by the temperature detecting member becomes a first temperature, and a condition where the predetermined period elapses after the power is turned on, is satisfied, the control device turns off the heat source and then drives the driving source, wherein, in a case where the temperature detected by the temperature detecting member when the power is turned on is higher than a second temperature, the control device waits for a predetermined waiting period after the power is turned on to turn on the heat source, and wherein the more the temperature detected by the temperature detecting member when the power is turned on increases, the more the control device lengthens the waiting period.
