ABSTRACT:
An electrophotographic copying apparatus has a rotatable photoreceptor having a photoconductive outer layer. An optical scanning arrangement includes an illuminating system and an optical system for projecting a light image from an original onto the photoreceptor. A developing system is provided for developing the latent image into a visible toner powder image, together with a transferring arrangement for transferring the toner powder image onto a copy paper sheet. A fixing arrangement is provided for fixing the transferred visible toner powder image on a copy paper sheet. A housing is provided which contains the photoreceptor, the optical scanning arrangement, the developing system, the transferring arrangement, and the fixing arrangement. Mounted within the housing are a first motor for the photoreceptor drum, a second motor for the optical scanning arrangement, a third motor for the developing system, and a fourth motor for the fixing arrangement. Each of the motors is of a flat type coreless motor disposed with its output shaft extending inwardly of the housing.
