摘要： An image forming apparatus, a feeder for an image forming apparatus and control method where: a feeding section feeds loaded papers to a main body of the image forming apparatus; a memory stores driving characteristic data of the feeding section; a function discrimination section discriminates a type of function to be performed by the feeding section; and a controller generates control data for controlling the feeding section to operate according to the discriminated type of function, based on, for example, the driving characteristic data. The control data is stored in a memory, and the driving of the feeding section is controlled by use of the stored control data when an execution command for a certain function is received from a main body control part. The control program, the controller, and the circuit board being utilized in the feeder additionally connected to the image forming apparatus may be generalized, whereby development and manufacture of the feeder may be facilitated.
