Abstract
A laser beam printer includes a beam deflector for selectively exposing a surface of a drum-like photoreceptor to form an electrostatic latent image thereon, a developer for depositing toner powder to the latent image, a transfer charger for transferring the developed image onto paper, and a tray for sequentially stacking paper sheets carrying the transferred images thereon. Since the transfer charger is disposed above the photoreceptor to face it, the image is transferred on a lower surface of the paper. After the image is transferred to paper, the paper is delivered to the tray by delivery rollers. The transfer charger and the delivery tray are mounted on a pivotal door, thus enlarging a space between the photoreceptor and the transfer charger.
