Abstract
An electrophotographic image forming apparatus includes a drum cartridge with an image bearing member and charging device for charging a surface of the image bearing member. The apparatus further includes a rotary supporting a plurality of developing devices each having a developer carrying member for developing an electrostatic latent image formed on the image bearing member, with the rotary being swingably mounted to the main assembly of the apparatus through a supporting member and being rotatable, relative to the supporting member, to bring the developing device to a developing position for developing the electrostatic latent image. A spacer member is provided for spacing between the charging device and the surface of the image bearing member, the spacer member being mounted between the image bearing member and the charging device.
