で、これを解決する対策が必要である。In an image forming apparatus, a latent image is formed by an exposure means on a drum that is uniformly charged by a pre-charger, this is developed by a developing device, and the developed toner image is transferred to recording paper by a transfer device. A recorded image is obtained by fixing. In this case, if the toner flying up from the developing device stains the wires and meshes of the pre-charger, it will cause black streaks, etc., so a measure to solve this problem is required.
そのため、従来は、ドラムが組み込まれるケース自体に
トナーを遮断する構造を持たせたり、ケースにマイラ等
を張り付けて遮断を行っていた。For this reason, conventionally, the case itself in which the drum is incorporated has a structure for blocking the toner, or the case is covered with Mylar or the like to block the toner.
