Abstract
A processor causes a transmission circuit to output a carrier signal intermittently. Each time the carrier signal is output, the processor determines whether or not a level of a detection signal is in a satisfactory state. In a first case where the level of the detection signal is determined to be in the satisfactory state, the processor performs a read control to cause the transmission circuit to perform a precharge process and a transmission process. In a second case where the level of the detection signal is not determined to be in the satisfactory state, the processor determines that the unit attachment portion is in a unit non-attachment state. In the first case, when the processor succeeds in identifying the developer information, the processor determines that the unit attachment portion is in a unit attachment state, and otherwise, determines that the unit attachment portion is in an exceptional state.
