Image forming system and image forming apparatus

摘要

An image forming system comprises an image forming apparatus including attach/detach sections to/from which a developer container for containing developer is attachable/detachable and an image bearing body for bearing a latent image; and a computer capable of communicating with the image forming apparatus and having a driver capable of instructing the apparatus to execute at least either single-color-image formation or color-image formation. When a developer container is attached to each attach/detach section, the apparatus is usable as a color image forming apparatus for forming color images by developing the latent image on the image bearing body with the developer in each developer container. When a developer container is attached to only one attach/detach section, the apparatus is usable as a single-color image forming apparatus for forming a single-color image by developing the latent image on the image bearing body with the developer in the developer container. The apparatus forms an image when the driver instructs the apparatus that is being used as the color image forming apparatus to execute single-color-image formation. The apparatus does not form an image when the driver instructs the apparatus that is being used as the single-color image forming apparatus to execute color-image formation.
