IPC: G06F9/48
Filed: 1987-04-27
Abstract: PURPOSE:To shorten the interrupt handling time by reading out contents of interruption request priority display means of an interruption request priority control circuit by a microprocessor to determine whether an interruption request should be permitted or not.

The rotating direction and the speed of the sleeve 30 are set to forward feeding rotation and the circumferential speed 5-10 times as high as that of the drum, respectively. The exposing position by the exposing means 2 is set to the downstream side in the drum rotating direction from the position where the developer comes closest. Namely, the circumferential speed of the sleeve 30 is made high, the density of the developer is made very large in an electrostatic charging area, the exposing position is set to the downstream side, and the density of the developer is relatively made small in an exposing and developing area. Therefore, the smooth electrostatic charging is attained and the high definition image is obtained.
