Image forming apparatus and method of controlling the same

A method of controlling an image forming apparatus comprising:

• determining whether a transfer roller initialization command has been generated;
• and
• upon determining that the transfer roller initialization command has been generated, transferring a developing agent to a surface of the transfer roller and filling a plurality of cells formed at the surface of the transfer roller with the developing agent to initialize the transfer roller.

An image forming apparatus comprising:

• a transfer roller;
• and
• a controller to control the transfer roller such that a developing agent is transferred to a surface of the transfer roller and a plurality of cells formed at the surface of the transfer roller is filled with the developing agent to initialize the transfer roller upon determining that the transfer roller is new.
