Patent ID: 7035568

Claim:
An image forming device comprising: a main casing including a front surface and a rear surface on opposite sides thereof, the main casing further having an upper surface, the rear surface being formed with a sheet discharge opening; an image forming section disposed within the main casing and including: an input reception unit that receives image data from an external source; and a process unit including: a process cartridge, the process cartridge including an electrostatic latent image bearing member; and an electrostatic latent image forming unit that forms an electrostatic latent image on the electrostatic latent image bearing member based on the image data received by the input reception unit, the process cartridge further including a developing agent supply unit that supplies developing agent to the electrostatic latent image bearing member to develop the electrostatic latent image on the electrostatic latent image bearing member into a visible image using the developing agent, the process cartridge being attached to and detached from the main casing through the front surface of the main casing; an image reader section disposed on the upper surface of the main casing and above the image forming section and including: an image reader that picks up image information from a document; a document transport mechanism that transports the document past the image reader in a direction from the rear surface to the front surface of the main casing; and an output unit that outputs the image information to an external device; a sheet supply unit that supplies a sheet to the process unit and that is located at a lower section of the main casing, the sheet supply unit being attached to and detached from the main casing through the front surface of the main casing, the process cartridge further including a transfer unit that transfers the visible image from the electrostatic latent image bearing member onto the sheet from the sheet supply unit; a sheet discharge unit that discharges the sheet with the visible image rearward through the discharge opening in the main casing; and a sheet discharge tray provided to the outside of the main casing at a position under the discharge opening, the sheet discharge tray holding the sheet discharged through the discharge opening.
