摘要： To provide an image forming apparatus (100) that is capable of quickly, appropriately, and uniformly controlling a transfer belt (5), does not have transfer current leakage even under a high humidity environment, and is capable of ensuring good transfer performance and separation performance.
A photosensitive drum (41) that supports an image to be transferred to paper; the transfer belt (5) that is opposed to the photosensitive drum and forms a nip; and a first heater (181) and a second heater (182) that heat the transfer belt (5) are provided, and the first heater (181) has higher performance to uniformly heat an entire area of the transfer belt (5) than the second heater (182); and the second heater (182) has higher performance to respond to a temperature change of the transfer belt (5) in a case of output change than the first heater (181).

摘要： To provide a cleaning apparatus, an image forming apparatus (100), and a program in which toner on a transfer member (5) can be cleaned at low cost without affecting an existing structure.
The cleaning apparatus includes: a main brush (51) that cleans and removes toner existing on a transfer belt (5); a high-voltage power source (51b) that applies voltage to the main brush (51); a determining means (190) that determines whether a condition that voltage applied to the main brush (51) exceeds a predetermined threshold is satisfied at a main brush nip (NP1) formed by the main brush (51) and the transfer belt (5) contacting each other; and a controlling means (190) that controls the voltage applied to the main brush (51) by changing bias current of the high-voltage power source (51b), wherein in a case where the determining means (190) determines that the condition that the voltage applied to the main brush (51) exceeds the predetermined threshold is satisfied, the controlling means (190) controls the voltage applied to the main brush (51) so as not to exceed the predetermined threshold by changing the bias current when the sheet contact area (5p) passes through the main brush nip (NP1).
