Abstract
An image forming apparatus comprises an optical system for regenerating an original manuscript; a regenerating member capable of regenerating the original manuscript in different modes; a means for setting the position of the optical system in accordance with respective modes; a detector for detecting information relating to the respective modes from the set position of the optical system, and a control device for controlling the regenerating member in accordance with the detected information by the detector. A protective apparatus is further provided which comprises a process load; a detector for detecting a continuous operation time of the load from the power frequency of an a.c. current supplied to the load, and a control device for controlling the operation of the process load in accordance with the output from the detector. The process load may be a lamp for exposing light on an original manuscript.
