摘要： A print medium feeding apparatus, comprising: a knockup plate on which a ream of print medium is stacked thereon; a pickup roller for picking up a sheet of print medium stacked on the knockup plate; a sheet separation member installed in a manner to form a contact nip with the pickup roller, and supplying friction force for separating the print medium sheet by sheet; and a friction pad disposed at an upper side of the sheet separation member, being in front of the contact nip. The print medium feeding apparatus of the present invention features an improved paper feeding capacity in that variable friction force is applied for separating printing medium. Moreover, since the friction pad does not come in contact with the pickup roller, the abrasion rate of the friction pad is much reduced. Furthermore, the material cost can be reduced by reducing the size of the friction pad.

摘要： A paper cassette for an image forming apparatus includes a cassette body, a pair of aligning plates, paper separating fingers, and a biasing member. The cassette body has a knock-up plate on which paper is stackable. The pair of aligning plates are disposed on the paper cassette body and moving in a widthwise direction for aligning paper stacked on the knock-up plate in the widthwise direction. The paper separating fingers are disposed on the aligning plates and are vertically movable to a predetermined distance above the aligning plates, for pressing against two corners of a leading edge of an uppermost sheet of paper stacked on the knock-up plate. The biasing member is connected to at least a side of one of the paper separating fingers, for increasing a relative downward pressure exerted by the paper separating finger on the uppermost sheet of paper stacked on the knock up plate.

摘要： A method and apparatus for removing remaining toner from an image forming apparatus, when a non developing time is detected during a performing of printing, a supply voltage applied to a supplying roller is increased to a level higher than a developing voltage applied to a developing roller. When the supplying roller having the supplying voltage of a voltage level higher than the developing voltage is in contact with the developing roller, electric flux is directed from the supplying voltage having a high electric potential to the developing voltage having a low electric potential due to a difference of intensities of electric fields between the supplying roller and the developing roller, while toner having negative charge moves from the developing roller to the supplying roller in a reverse direction to that of the direction of the electric flux to remove the remaining toner.
