    摘要: A data transfer apparatus, system and method using the same are provided. A data transfer system according to an exemplary embodiment includes a user process space, a kernel space and a hardware space. A plurality of user processes are executed in the user process space. The kernel space includes a kernel thread. The hardware space performs an input/output according to the input/output request of the each user process. When input data based on the input request are received to the hardware space, the data transfer system checks whether the user process requesting the input is in an execution state, and allows the kernel thread to copy the input data from the kernel space to the user process space when the user process is in the execution state.

The image forming apparatus includes a plurality of photosensitive bodies having transfer points to transfer images onto a transfer object, a driving source to drive at least two photosensitive bodies of the plurality of photosensitive bodies, and a driving gear train to transmit driving power from the driving source to the at least two photosensitive bodies. The driving gear train includes photosensitive body shaft gears respectively connected to the photosensitive bodies driven by the driving source, and connecting gears to transmit the driving power to the photosensitive body shaft gears. When any one of the photosensitive body shaft gears is set to a reference photosensitive body shaft gear, the number of teeth of the connecting gear, which is disposed at a jth position from the reference photosensitive body shaft gear, is determined so that a value calculated from the following equation is substantially an integer. L π ⁢ ⁢ D · 1 R j Here, D refers to a diameter of each of the photosensitive bodies, L refers to a distance between the transfer points of two adjacent photosensitive bodies, and Rj refers to a speed reduction ratio from the jth connecting gear to the reference photosensitive body shaft gear.
