Abstract
An image forming apparatus configured to, in a case where a difference between a charging current flowing through a first charging roller and a charging current flowing through a second charging roller is larger than a first threshold value, perform first cleaning processing in which a cleaning ability of one cleaner of a first cleaner and a second cleaner, which corresponds to one of the first charging roller and the second charging roller, is lower than a cleaning ability of another cleaner of the first cleaner and the second cleaner, which corresponds to another of the first charging roller and the second charging roller, a charging current flowing through the one charging roller being larger than a charging current flowing through the other charging roller.
