Official abstract text for this publication.
In an image forming apparatus, photosensitive bodies are mounted in a first frame. Developing units are detachably mounted in the first frame. A second frame is movable relative to the first frame. Each developing unit is movable relative to the first frame between a separate position, at which a developing roller is separate from a photosensitive body, and a contact position, at which the developing roller is in contact with the photosensitive body. The second frame moves relative to the first frame, thereby moving the developing units relative to the first frame between the separate positions and the contact positions. The second frame positions each developing unit relative to the first frame in a direction to move the developing roller toward the corresponding photosensitive body when the developing unit is in the contact position.
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus, comprising: a first frame, a plurality of photosensitive bodies being mounted in the first frame such that the photosensitive bodies are juxtaposed with one another, a plurality of developing units being detachably mountable in the first frame in correspondence with the photosensitive bodies; and a second frame that is movable relative to the first frame, wherein each developing unit of the developing units includes a respecti…
