Patent ID: 8195065

Claim:
An image-forming apparatus comprising: a first exposing unit provided below a first image carrier, that irradiates exposing light to the first image carrier; a partition member that separates a space in which the first exposing unit is provided from a space in which the first image carrier is provided, the partition member comprising: a first light-passing part that allows exposing light irradiated by the first exposing unit to pass through the partition member, and that extends in a direction in which a first developing unit is attached to or detached from the image-forming apparatus, the first developing unit being a unit that develops a latent image carried by the first image carrier, using color materials supplied through a first supply opening of the first developing unit; and a first protrusion part that extends along the first light-passing part, wherein the first light-passing part, the first protrusion part, and a part of the partition member located below the first supply opening of the first developing unit attached to the image-forming apparatus are arranged in an order of the first light-passing part, the first protrusion part, and the part of the partition member located below the first supply opening; and an image-transferring unit that transfers an image developed by the first developing unit to a medium, wherein: the partition member further comprises a recess part that extends in the direction in which the first developing unit is attached to or detached from the image-forming apparatus; and the first light-passing unit, the first protrusion unit, and the recess part are arranged in an order of the first light-passing unit, the first protrusion unit, and the recess part.
