In an image forming apparatus configured to form a toner image on a photoconductive element and transfer it to a recording medium of the present invention, the photoconductive element and an image transferring member pressed thereagainst are constructed into an image transferring unit. The convergence yoke portion 5 comprises an annular convergence core 53, a convergence horizontal coil 51 wound around both of left and right two regions of the core 53 which intersect a horizontal axis, and a convergence vertical coil 52 wound around both of upper and lower two regions of the core 53 which intersect a vertical axis. In one embodiment the terminals of the diode are separated by a second dielectric-filled trench and sidewall region. According to the detection signal, the mail receiver sends a command ordering the rearrangement of the mail data.
