Abstract
A copying machine is capable of making a portion of a copy corresponding to a specific area of a document highlightened, more specifically, capable of giving suitable contrasts among areas of the copy corresponding to the areas of the document, when those areas have different degrees of importance, and capable of forming characters on a copying paper readily without an input device, such as a word processor keyboard which requires significant modifications on the copying system.
