Abstract
Abstract An image formation apparatus has a first feeder for feeding a copy sheet from a container containing a number of copy sheets therein, a second feeder for feeding a copy sheet supplied manually thereto. Both feeders feed the copy sheet to an image formation station, and a scanner exposure-scans an original image to form a copy image, a first detector detects the size of manually supplied copy sheets and a second detector detects the size of the copy sheets in the container, a controller controls the movement of the scanner in accordance with detection by the first and second detectors, so that the scanning stroke length of the scanner is coordinated for the size of the copy sheet manually supplied to the image formation station and supplied from the container.
