Electrophotographic copying apparatus having capability of interrupting a copy operation in midst of multi-color transfer process

摘要

The electrophotographic copying apparatus permits interrupting a copying operation for changing copying conditions to be inputted in the midst of multi-color transfer process. When an interrupt instruction is inputted the apparatus does not continue its operation, and the copying paper incompletely copied is discharged immediately after the transfer operation in progress so as to proceed to the next operation promptly. Further, the apparatus does not count the discharged paper as a completely copied one so that a user may not be charged.
