IMAGE FORMING APPARATUS: abstract simplified (18192255)

• This abstract for appeared for patent application number 18192255 Titled 'IMAGE FORMING APPARATUS'

Simplified Explanation

The abstract describes an image forming apparatus that includes multiple photoconductors and exposure units. Each exposure unit has a substrate with light emitting portions to expose the photoconductors, and a duct to guide airflow for cooling the substrate. A fan generates the airflow, and a duct unit connects to the ducts of the exposure units through different openings. The first opening, which is the longest flow path from the fan, has a larger area than the second opening, which is the shortest flow path from the fan.

Original Abstract Submitted

An image forming apparatus comprising: a plurality of photoconductors; a plurality of exposure unis each corresponding to a different one of the plurality of photoconductors, each of the plurality of exposure units including a substrate on which a plurality of light emitting portions configured to emit light to expose the photoconductors, and a duct configured to guide an airflow that cools the substrate along the substrate; a fan configured to generate the airflow that cools the substrate; and a duct unit configured to communicate with the ducts of the plurality of exposed portions via different ones of a plurality of openings, wherein an area of a first opening that is a longest flow path from the fan among the plurality of openings is larger than an area of a second opening that is a shortest flow path from the fan among the plurality of openings.
