Abstract
An electrophotographic printer, in particular for printing individual sheets, contains one or more printing modules (10/1 to 10/4) in which the printing apparatus for carrying out the electrophotographic process are constructionally combined. The printing modules are designed as separate constructional units for mounting in a housing of the printer and have fitting elements (32, 33) for arranging the printing modules (10/1 to 10/4) in rows in the housing (34) in an exactly fitting manner. Each printing module (10/1 to 10/4) contains an intermediate carrier (14) with associated fixing elements in order to transfer a toner image, produced on a photoconductive drum (11) onto a recording carrier (15) and to fix there. The printer can be upgraded from a single-color simplex printer to a multi-color duplex printer by multiple arrangement of the printing modules.
