Abstract:
An image forming apparatus has a power supply circuit including a power circuit, a main circuit, and a sub-circuit. The sub-circuit includes a timer that performs electrical conduction of a driving contact point of a heater by a first setting time and performs electrical conduction of a driving contact point of a discharge fan by a second setting time when a power switch is turned off. When it is determined that humidity in an image forming apparatus body detected by a humidity detection sensor is equal to or more than a threshold value, the first setting time is set to 0 and the second setting time is set to a predetermined time larger than 0. When it is determined that the humidity is less than the threshold value, the first setting time is set to a predetermined time larger than 0 and the second setting time is set to 0.

Claim (Index 1):
An image forming apparatus including an image forming apparatus body, a power switch, a control unit for controlling an image forming operation in a state in which the power switch is turned on, and a power supply circuit for supplying power to the control unit, the image forming apparatus further comprising:\n a heater that heats a predetermined place in the image forming apparatus body; a discharge device that discharges water vapor in the image forming apparatus body to an exterior; and a humidity detection sensor that detects humidity in the image forming apparatus body or humidity associated with the humidity, and transmits information on the detected humidity to the control unit, wherein the power supply circuit comprises: a power circuit connected to a power supply; a main circuit including the control unit; a sub-circuit including the discharge device and the heater; and a switching circuit that connects the power circuit to the main circuit when the power switch is turned on and connects the power circuit to the sub-circuit when the power switch is turned off, the sub-circuit comprises: a driving contact point of the heater; a driving contact point of the discharge device; and a timer that performs electrical conduction of the driving contact point of the heater by a first setting time and performs electrical conduction of the driving contact point of the discharge device by a second setting time when the power switch is turned off, and the control unit is configured to perform timer setting control for determining whether the humidity in the image forming apparatus body is equal to or more than a threshold value on the basis of humidity information received from the humidity detection sensor, for setting the first setting time in the timer to 0 while setting the second setting time to a predetermined time larger than 0 when it is determined that the humidity is equal to or more than the threshold value, and for setting the first setting time in the timer to a predetermined time larger than 0 while setting the second setting time to 0 when it is determined that the humidity is less than the threshold value, in a state in which the power switch is turned on.
