ABSTRACT:
Image forming methods and apparatuses capable of performing stable and fast sheet transfer operations are provided. In a continuous feed mode, a preceding sheet and a succeeding sheet are successively fed from a sheet tray through first and second transfer rollers to an image forming position. When it is determined that a trailing edge of the preceding sheet has passed the first transfer roller, the driving of the first transfer roller is stopped for a predetermined time period. As a result, the preceding sheet and the succeeding sheet are transferred with a desired sheet interval while suppressing sheet interval variations.
