Image formation apparatus, image formation method, and computer product |
摘要 |
At least two image formation devices are provided. Each image formation device has a writing optical device that forms a latent image on a photosensitive member and a developing device that develops the latent image into a visual image. If the writing optical device in one of the two image formation devices is broken down, then the latent image is formed using the writing optical device in other of the two image formation devices. The latent image is developed to obtain the visual image using the developing device of the image formation device with the broken writing optical device.
