問題点があった。As a countermeasure against this, for example, a large electromagnetic solenoid 111 may be used, or the suction stroke of the plunger 111A may be set short. In the former case, however, the cost of the image forming apparatus is increased, and in the latter case. In this case, there is a problem that the configuration for switching the branch conveyance path switching member 107 between the first setting position and the second setting position by the short suction stroke of the plunger 111A becomes difficult.
