Abstract
An image forming apparatus includes a fixing device, control circuitry, and a controller. The fixing device includes a first rotating body, a second rotating body in pressure contact with the first rotating body, and a heat source to heat the first rotating body. The circuitry, at startup of the fixing device, causes the fixing device to perform a rotating operation to rotate the first rotating body while causing the heat source to perform a heating operation to heat the first rotating body, thereby performing a fixing startup operation to raise a temperature of the first rotating body. The circuitry delays at least one of a timing for start of the rotating operation and a timing for start of the heating operation to be later than a start of a controller startup operation such that the fixing startup operation is completed in time with completion of the controller startup operation.
