摘要： An image forming apparatus having: a power source applying alternating current voltage to the magnetizing coil; a demagnetizing coil switchable between a conductive state and a cutoff state, and when in the conductive state, cancelling out a portion of a magnetic flux produced by the magnetizing coil; a contact switch and a semiconductor switch electrically connected in parallel, and, in combination, bringing the demagnetizing coil into the conductive state or the cutoff state; and a control unit opening or closing the switches separately. The control unit: opens or closes the semiconductor switch in synchronization with a zero-crossing of the alternating current voltage at least when the contact switch is open; opens or closes the contact switch only when the semiconductor switch is closed; and opens the semiconductor switch when the demagnetizing coil brought into the conductive state by the contact switch needs to be maintained in the conductive state.

摘要： An image formation device for executing a printing job to form a toner image on a record sheet includes: an operation panel configured to move between a first position at which the operation panel protrudes from a front of a device body and a second position at which the operation panel is retracted to a device body side with respect to the first position. The device further includes an acquisition device configured to obtain state information indicating a state of the device body; and a hardware processor configured to determine, based on the obtained state information, whether the state of the device body is a state requiring a user access to the device body or a state of accessing to the device body. The device retracts the operation panel to the second position when a determination result is positive.
