摘要： An image forming apparatus includes a fixing portion, a temperature detection portion, a power supply portion, a control portion, a photovoltaic module and a power storage/supply portion which stores power from the photovoltaic module and which performs power supply to the temperature detection portion when power supply from the power supply portion to the temperature detection portion is stopped. The control portion detects, when a return condition is satisfied, the temperature of the fixing portion based on the output of the temperature detection portion, and as a temperature on return is higher, the control portion starts fixing return processing at later timing whereas as the temperature on return is lower, the control portion starts the fixing return processing at earlier timing.

摘要： An image forming apparatus includes a fixing unit and a fixing process managing system. The fixing process managing system, including a mode switchover unit, controls a time mode and a temperature mode for heating a fixing member. In the time mode, the fixing unit is determined to be ready for a fixing process when a given time elapses after activation of the image forming apparatus. In the temperature mode, the fixing unit is determined to be ready for a fixing process when a temperature of the fixing member attains a given reference temperature after activation of the image forming apparatus. The mode switchover unit selects between the temperature mode and the time mode. The fixing process managing system selects the temperature mode instead of the time mode when a supply amount of electrical power to the fixing unit is determined to be below a required electrical power supply level.

摘要： An image forming system includes an image forming apparatus including an AC-DC converter and a main board, and a sub board having a sub connector connectable with a main connector of the main board. When the sub board is not connected with the main board, a main DC-DC converter on the main board converts a DC voltage from the AC-DC converter into a first DC voltage and output the first DC voltage to a circuit element for image formation. When the sub board is connected with the main board, the AC-DC converter outputs the DC voltage to a sub DC-DC converter on the sub board via the main connector and the sub connector, and the sub DC-DC converter converts the DC voltage from the AC-DC converter into a second DC voltage and output the second DC voltage to the circuit element via the sub connector and the main connector.
