ABSTRACT:
An image forming apparatus for forming an image onto a sheet includes a sheet supporting member; a charger which is positioned in a vicinity of the sheet supporting member; and a device for controlling the charger so that the charger charges a specific portion of the sheet supporting member corresponding to a leading edge portion of the sheet to an electrostatic potential higher than that of a remaining portion of the sheet supporting member. A method of adhering a sheet to a sheet supporting member during an image forming process includes charging a specific portion of the sheet supporting member corresponding to a leading edge portion of the sheet to a first electrostatic potential; charging a remaining portion of the sheet supporting member to a second electrostatic potential that is lower than the first electrostatic potential; and delivering the sheet to the sheet supporting member so that a leading edge portion of the sheet is aligned with the specific portion of the sheet supporting member.
