Abstract
In a copier having a sheet pick-up roller for picking up sheets one by one from a paper cassette, and a writing section, where an image is written on the sheet, a sheet separation mechanism is disposed between the sheet pick-up roller and the writing section to separate the sheets when a plurality of sheets are picked up in superposition. A sensor is disposed between the separation mechanism and the writing section, the initiation of the writing is timed to occur with the arrival, at the writing section, of the leading end of the area of the sheet in which the toner image is to be written.
