ABSTRACT:
For an image forming apparatus operable according to the electrographic method or magnetic recording method, it is proposed to form, as respective detachable units, some components of the apparatus for the purpose of easy exchange of wasted and consumed parts, multiple-purpose utilization of the main apparatus and simplification of maintenance. The present invention is a development of this idea. According to the invention there is provided such detachable unit which has in itself a function to change all or a part of the image forming conditions required to the main apparatus to which the unit is to be incorporated. When the unit is mounted into the main apparatus, data of characteristics of the unit and image forming condition suitable for the selected application of the apparatus can be set automatically. Since the unit itself has a part useful for setting the necessary image forming conditions, it is no longer necessary for the serviceman or the operator to do troublesome works for change of conditions and adjustment of the apparatus every time of unit exchange. A desired image can be obtained at once after mounting the unit into the main body of apparatus.
