Process unit and exposure unit arrangement in an image forming apparatus

摘要

An image forming apparatus includes: a process unit having a photosensitive body extending in a first direction; a first roller disposed on one side in a second direction of the process unit, which is substantially perpendicular to a vertical direction and the first direction; an exposure unit; a fixing unit disposed on the other side in the second direction of the process unit; and a second roller disposed on an upper side of the fixing unit and on the other side in the second direction of the first roller and configured to transport the recording medium passed through the fixing unit to an outside of a casing. The casing includes a guide portion configured to guide the process unit into the casing, and the exposure unit is disposed on the one side in the second direction of the process unit and the guide portion.

1. An image forming apparatus comprising:
a casing; a process unit which is configured to be removably mounted to the casing, and is configured to form a developer image on a recording medium, the process unit including a photosensitive body extending in a first direction which intersects a vertical direction; a cassette which is disposed on a lower side in the vertical direction with respect to the process unit, and is configured to accommodate recording media to be supplied to the process unit; a first sheet feed roller which is disposed on one side in a second direction with respect to the process unit, and is configured to separate the recording media in the cassette one by one, the second direction being substantially perpendicular to the vertical direction and the first direction; an exposure unit which is configured to expose the photosensitive body; a fixing unit which is disposed on another side in the second direction with respect to the process unit, and is configured to fix a developer image formed on a recording medium by the photosensitive body; and a sheet discharge roller which is disposed on an upper side in the vertical direction with respect to the fixing unit and on the other side in the second direction with respect to the first sheet feed roller, and is configured to transport the recording medium passed through the fixing unit to an outside of the casing, wherein the casing includes a guide portion which is configured to guide the process unit into the casing, wherein the exposure unit is disposed on the one side in the second direction with respect to the process unit and the guide portion, and wherein the exposure unit is disposed on the upper side in the vertical direction with respect to the first sheet feed roller so as to overlap the first sheet feed roller when the exposure unit is projected in the vertical direction.
