Claims

[Scope of utility model registration request]

A projection device that projects an original image toward a document table of an electronic harp copying device, a copy of an optical image projected by the projection device on the document table, and a reflected optical image of the document placed on the document table. In the electrophotographic copying apparatus configured to perform copying, a reflective sheet can be disposed so as to surround an optical image projected from the projection device onto the document table in at least one direction along a periphery of the document table. The reflective sheet is configured to be able to observe a projected image projected from a projection device onto a document table, and in a positive original projection copying process using the projection device, the reflective sheet is exposed to light from a light source for exposing a reflective optical image. An electrophotographic copying apparatus characterized in that blank exposure is performed using a blank exposure method.
