Image recording apparatus provided with exposure unit using cathode ray tube

摘要

An electrophotographic printer having a movable image developing device for forming a visible image on a photosensitive sheet. The printer contains a sheet handling unit having a light receiving portion for feeding the photosensitive sheet to the light receiving portion and for discharging the same therefrom; an exposure unit containing a cathode ray tube which projects its displaying image onto the photosensitive sheet when the sheet is at the light receiving portion so as to produce an electrostatic latent image on the sheet; and, the image developing device selectively movable between first and second positions, the developing device containing a developer for developing the electrostatic latent image into the visible image with the developer. A copying apparatus is also disclosed whose CRT in an exposure unit has a scrolling function. The copying apparatus also provides a control for controlling scrolling speed in synchronization with the feeding speed of the sheet. The CRT used in the above described device has a screen whose edge portion provides brightness higher than that of the remaining portion.
