摘要： An image forming apparatus includes first and second developer carrying members and a control device. The apparatus is operable in a first mode where an image of a single color is formed using the first developer carrying member and is operable in a second mode, wherein an image of a plurality of colors is formed using the first and second developer carrying members. The control device controls a first discharging operation for discharging developer from the first developer carrying member and a second discharging operation for discharging developer from each of the first and second developer carrying members. When the apparatus executes only the first mode, the control device performs more image formations, in a period between completion of the second discharging operation and start of the first discharging operation, compared to a period between completion of the first discharging operation and start of a subsequent first discharging operation.

摘要： A delay test system includes an electronic circuit, such as a normal circuit which has a portion to be tested and a plurality of flip-flop circuits. In this event, each of flip-flop circuits is serially connected to each other to perform a delay test for said normal circuit. Further, a first clock input terminal is connected to the flip-flips and a normal circuit to input a normal mode clock signal. Moreover, a second clock input terminal is connected to the flip-flop circuits and the normal circuit to input a test clock signal. With such a structure, an input and output operation of data signals is carried out in synchronism with edge timings determined by both the normal mode clock signal in the normal mode on the condition that the test clock signal is not supplied to the second clock input terminal. On the other hand, the first and second clock input terminals are separately driven by the normal mode clock signal and the teat clock signal in the test mode. Consequently, a delay test is carried out by the use of a timing difference between an edge timing of the normal mode clock signal and an edge timing of the test clock signal.

摘要： A test method sets a write value to a scan flip-flop for setting a value to a memory to be tested. It then performs a series of shift operation in scan paths until setting of a read value is completed. During the shift operation, a value for refresh operation is added to the value passing through the flip-flop for setting a value to the memory to be tested.
