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