Abstract
An image forming apparatus includes a photoconductive drum, a transfer roller configured to transfer a visible image formed on the photoconductive drum to a sheet, and a processor. The processor is configured to acquire an interruption time, which is measured after a process including charging of the photoconductive drum is interrupted, and is equal to an amount of time elapsed while the photoconductive drum is in a charged state, determine a cleaning time depending on the interruption time, and execute a cleaning process on the transfer roller for the duration of the cleaning time.
