Sharp Kabushiki Kaisha, David G Conlin, David A Tucker, Dike Bronstein Roberts & Cushman, April 10, 2001: US06215968 (14 worldwide citation)

A high density detecting toner pattern is formed on a photosensitive body and a high density correction is effected by comparing a value detected by a reflection sensor with a high density reference value so as to maintain an image density at a specific level. An image density correcting section ado ...

Before replacement of constituent parts of an image density sensor or of other image forming units, the image density of a formed test toner patch image is detected by the image density sensor and conditions for image formation are controlled. After replacement of the constituent parts, the image de ...
