发明名称 Method and apparatus for image forming capable of effectively collating a stack of single-/double-sided recording sheets in a desired ejection tray
摘要 An image forming apparatus includes first and second image carrying members, ejection trays, and a sheet transferring mechanism. The first image carrying member carries images in increasing order of corresponding sheet numbers. The second image carrying member carries an image transferred from the first image carrying member. The ejection trays include a first ejection tray, which stacks output sheets in a straight or forward orientation, and a second ejection tray, which stacks output sheets in a reversed orientation. The sheet transferring mechanism transfers a recording sheet to the first and second image carrying members. The first and second image carrying members transfer images onto both first and second surfaces of the recording sheet, at the same time, in response to a selection between the first and second ejection trays in a double-sided recording mode so that the first and second ejection trays stack the recording sheets in increasing order of page numbers.
