IMAGE FORMING APPARATUS, PROGRAM, AND LIFE DETERMINATION METHOD
FIG2 is a block diagram showing a functional configuration of the image forming apparatus according to the present invention
As shown in FIG2, the controller 10 is configured by including a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, and the like. The CPU 101 reads out a program corresponding to the processing contents from the ROM 102, loads the program onto the RAM 103, and integrally controls the operations of the components of the image forming apparatus 100 in cooperation with the loaded program. At this time, various types of data stored in the storage 17 are referred to.

['13. The image forming apparatus according to claim 12, wherein the life determiner calculates an average value of the movement speed of a predetermined number of sheet which is detected by the speed detector and stores the average value in a storage (17), and if the tray is detected being opened during the sheet feeding of the second sheet which is fed by the sheet feeding roller immediately after the first sheet, the life determiner deletes the average value which is stored in the storage.']
