Abstract:
An image forming apparatus is provided which includes a multiplexer (MUX) which is able to be connected to at least one developer supplier, at least one pull-up resistor which is connected in parallel to at least one connection line between the at least one developer supplier and the MUX, and a central processing unit (CPU) which detects a connection signal from the at least one pullup resistor and the at least one connection line, and determines whether an initial developer supplier is mounted according to the value of the connection signal.
