Patent ID: 7356283

Claim:
An image-forming apparatus comprising: a main device body having a first side surface and a second side surface opposite to the first side surface, an opening being formed in the first side surface; a cover configured to move between a closed position in which the cover covers the opening in the main device body and a fully opened position; a plurality of process cartridges configured to be mounted in or removed from the main device body through the opening, the process cartridges being arranged in a row in the main device body when the process cartridges are mounted in the main device body, each process cartridge comprising a developer-accommodating section, an image-holding member, and a developing member, the developer-accommodating section accommodating developer, the image-holding member forming an electrostatic latent image thereon, the developing member developing the electrostatic latent image onto a developer image by using the developer supplied from the developer-accommodating section, thereby allowing the image-holding member to carry the developer image thereon; an exposure device integrally provided on the cover and irradiating a light beam on each image-holding member to form the electrostatic latent image thereon, a conveying unit that conveys a sheet to a position opposing each image-holding member, thereby allowing the developer image to be transferred from each image-holding member onto the sheet; and a tray that supports the sheet after the sheet has been formed with the developer image from at least one of the image-holding members, wherein the cover has a side from which the exposure device emits light beams, the cover in the fully opened position allowing the side to face downward.
