For example, in the cleaning method (b), a detergent liquid (detergent liquid or detergent soln.) having 4 to 9 pH and about 0.1 to 30% concn. is used normally in a first tank 1-1. The detergent liquid is usually adjusted to 10 to 60 deg.C, and the tank is equipped with an ultrasonic cleaner in the inside. A second tank 1-2 has an almost the same structure. Most of the dirt, such as dust and oil depositing on the photoreceptor base body surface, is removed by cleaning in the first tank, and the base body is completely cleaned in the second tank.  The third to fifth tanks 2-1, 2-2, 2-3 are used for the process to wash off the detergent or the like used in the first and second tanks.

Abstract: PURPOSE:To avoid the ineffective holding of a circuit and to ensure a highly efficient communication, by detecting the presence or absence of the information equivalent to a scanning line of the received data when no carrier is detected at a modulating/demodulating circuit and then switching the circuit to the telephone side in case no information is available for the scanning line which is received normally. CONSTITUTION:While a picture signal is received, a carrier detection output 14 is inspected periodically or intermittently at a control part 7. A timer 8 starts its timing action for a certain period at a time point when the output 14 is turned off. Meanwhile a received data analyzing part 5 analyzes the received data 19 and then displays the receiving state signal if at least a scanning line is received normally. Then the timing action is stopped, and the timer 8 is cleared. If there is no scanning line which is received normally, a fault display is given to continue the timing action. If a receiving state signal 15 has a fault display at a time point when the time-out signal given from the timer 8 displays the time-out state, a circuit switch indicating signal 17 is delivered from the part 7. Thus a relay 9 is actuated to switch the circuit to the telephone side.
