Abstract
A developing unit or similar recording unit which is removably mounted on an image recording apparatus is provided with a constant voltage device or similar level adjusting means which has a particular characteristic matching with recording color of the recording unit. The level adjusting means changes the level of a power supply (e.g. voltage) fed from a body of the apparatus to a level particular to the recording unit, i.e., to the color of toner stored therein. Identifying such a particular level, the apparatus body automatically sets up process conditions which are optimum for the identified level. Hence, the level detected by the apparatus body changes depending upon the kind of a recording unit actually mounted on the apparatus body, whereby optimum process conditions are set up.
