Abstract
A cleaning apparatus includes: a brush that contacts a transfer member and cleans and removes toner existing on the transfer member; a constant current type voltage applier that applies voltage to the brush; and a hardware processor that determines whether a condition that voltage exceeds a predetermined threshold is satisfied at a nip formed by the brush and the transfer member contacting each other, and controls the voltage by changing bias current of the voltage applier, wherein the transfer member has a sheet contact area contacting a sheet on the transfer member and an inter-sheet area other than the sheet contact area on the transfer member, and in a case where the hardware processor determines that the condition is satisfied, the hardware processor controls the voltage so as not to exceed the predetermined threshold by changing the bias current when the sheet contact area passes through the nip.
