Abstract: An example image forming apparatus includes a power device, a photosensitive drum, a transfer device to remove remaining toner based on a cleaning bias voltage, an optical sensor to detect remaining toner, and a processor to adjust the cleaning bias voltage based on a set offset bias voltage. The processor may change a surface potential of the photosensitive drum to a voltage of a set pattern using the power device, acquire a size ratio of a periodic component based on a frequency of a signal detected from the remaining toner using the optical sensor, and, based on the acquired size ratio of the periodic component being greater than or equal to a set size ratio, adjust the cleaning bias voltage based on an offset bias voltage corresponding to the size ratio of the periodic component and provide the adjusted cleaning bias voltage to the transfer device to remove remaining toner.

Abstract: A memory system includes a read-only memory (ROM), a main memory and a processor. The ROM stores a basic input/output system (BIOS). The main memory includes a fail address table which stores at least one fail address designating a memory cell row having at least one defective cell. The processor receives fail information of the at least one fail address from the main memory and loads data associated with a booting operation of the memory system in a safe area of the main memory by avoiding a fail area corresponding to the at least one fail address during power-on operation while a power is applied to the memory system. The data associated with the booting operation is stored in a storage device.
