Patent number: 11971676Abstract: A processor derives a plurality of unit density values which are each an average value of sensed densities for each of a plurality of unit areas sectioned for each unit length in a test toner image. The processor derives a weighted average of the plurality of unit density values to derive a test image density used for adjusting a control parameter in a printing portion. The unit length is a greatest common factor of two target lengths corresponding to perimeters of two types of target rotating members out of the plurality of rotating members. When a number of the plurality of unit areas is represented by n, n is a value obtained by subtracting 1 from an added value of a first constant and a second constant. The first constant and the second constant are values obtained by respectively dividing the two target lengths by the unit length.Type: GrantFiled: January 30, 2023Date of Patent: April 30, 2024Assignee: KYOCERA Document Solutions Inc.Inventors: Masaru Watanabe, Yasuaki Sakamoto, Ayato Morikami, Kenichi Hayashi, Hideyuki Ogasawara, Yukiko Yoshimura
