摘要： An electrophotographic image forming apparatus usable with process cartridges. The apparatus includes mounting portions for detachably mounting the cartridges. In each mounting portion, a cartridge is inclined downwardly from an upstream to a downstream side with respect to a mounting direction and a phantom plane passing through axes of the drums is inclined toward a downstream side with respect to the mounting direction from a bottom part to a top part of the phantom plane. Parts of cartridges mounted to a lower one and the next higher one of the mounting portions overlap, as seen along a plane perpendicular to the phantom plane from an upstream side with respect to the mounting direction. The apparatus also has a light projector and a feeder for feeding recording material, and the cartridges are mounted to or demounted from respective mounting portions from above the perpendicular plane.

摘要： A developing device facing an image carrier and including a developer carrier, a developer flying control member, and a development-noise control member. The developing device develops an electrostatic image formed on the image carrier by causing the developer to fly from the developer carrier to the image carrier upon an application of an alternating-current bias to the developer carrier. Noise produced by the development-noise control member vibrated by an oscillating electric field of the alternating-current bias is smaller than a noise produced by the developer flying control member vibrated by the oscillating electric field.
