Abstract
An image forming apparatus in which parts of an image forming portion are formed as modular units, including, a section for driving the image forming portion, a section for detecting a signal representing a torque of the driving section, and a section for discriminating the attachment or detachment of the modular parts of the image forming portion according to the signal representing the torque detected by the detecting section. The load on the driving section, which is changed by the attachment of the modular parts of the image forming portion, is measured, and the attachment of a plurality of units can be checked by means of one attachment/detachment sensor without using many sensors for respective parts or units.
