摘要： An image-forming device includes a cleaning unit, a toner detection unit, a control unit, and a cleaning target member in the housing. The cleaning unit applies a predetermined voltage with a predetermined absolute value to the cleaning target member to remove toner from the cleaning target member through an electrostatic force. The toner detection unit detects an amount of toner on the cleaning target member at least twice to detect a first amount of toner and a second amount of toner. The first amount and the second amount of toner are detected when a first voltage having a first absolute value is applied as the predetermined voltage at a first time and when a second voltage having a second absolute value is applied as the predetermined voltage at a second time. The control unit determines the predetermined absolute value based on the first toner amount and the second toner amount.

摘要： A power device includes a transformer, a control signal outputting unit, and a power adjusting unit. The transformer has a primary coil and a secondary coil. The control signal outputting unit variably controls a parameter value and outputs, based on the parameter value, a control signal for controlling output power from the secondary coil. The power adjusting unit receives the control signal from the control signal outputting unit and adjusts power supplied to the primary coil based on the control signal. The power adjusting unit modifies a rate of change within a range in which the parameter value can be variably controlled, the rate of change being a rate of change in the power supplied to the primary coil with respect to the parameter value.
