An image forming apparatus has a direct print function by which application data is obtained from an external device so that image formation is performed. The image forming apparatus includes an obtaining unit, a classification unit, a discarding unit, a storage unit, an image processing unit and an image forming unit. The obtaining unit obtains the application data. The classification unit classifies the application data into use data used for the image formation and no-use data not used for the image formation on the basis of a predetermined setting related to the image formation. The discarding unit discards the no-use data. The storage unit stores the use data. The image processing unit generates print data on the basis of the stored use data. The image forming unit performs the image formation on the basis of the print data.
