Title: Electrophotographic copying method
Inventor: SAKAMOTO KOJI
IPC: G03G15/00
Filed: 1987-03-26
Abstract: PURPOSE:To form an image with an appropriate image tone by automatically controlling an exposure amount and/or a development bias voltage based on information about an original surface density grasped by a photodetecting means moving along an original surface so as to cross a scan direction and transferring an original. CONSTITUTION:The photodetecting means 36 is moved along the original surface so as to cross the scan direction of the original 12 due to the relative movement between an exposure means and the original while they are relatively moving. The means 36 is moved while the exposure means is scanning, and hence light from the original surface is detected to grasp the optical photographic density of the original surface. By such scanning, an original density detection and scan such as tracking a ruled line or an underline can be evaded. Thus the original density is precisely detected to obtain an image with an appropriate image tone.
