Patent number: 11092908Abstract: An image forming apparatus includes an image holding unit that holds an image that is formed of a developer, the image being intended to be transferred onto a medium, and an image that is not intended to be transferred onto a medium, a transfer unit that transfers the image that is intended to be transferred onto a medium onto a medium, a removing unit that removes the image that is not intended to be transferred onto a medium from the image holding unit, and a forming unit that forms the image that is not intended to be transferred onto a medium onto the image holding unit by using a developer and that has a first forming mode for a first medium and a second forming mode for a second medium that has a transfer sensitivity lower than a transfer sensitivity of the first medium, the forming unit being configured to use a larger amount of the developer in formation of the image that is not intended to be transferred onto a medium in the first forming mode than in the second forming mode.Type: GrantFiled: April 27, 2020Date of Patent: August 17, 2021Assignee: FUJIFILM Business Innovation Corp.Inventors: Masaaki Yamaura, Yoshiyuki Tominaga, Kotaro Araki, Ayumi Noguchi

Patent number: 11086250Abstract: An image forming apparatus includes an image carrier that carries an image, a developing unit that applies a developing voltage to develop an electrostatic latent image formed on the image carrier with a developer, a transfer unit that electrostatically transfers the image onto media of different types, and a development controller that controls a developing operation of the developing unit. The development controller has a first control mode for a first medium, and a second control mode for a second medium having a lower transferability than the first medium. In the first control mode, the developing unit applies the developing voltage according to a first developing condition. In the second control mode, the developing unit applies the developing voltage according to a second developing condition in which a developing property is reduced as compared with the first developing condition.Type: GrantFiled: May 7, 2020Date of Patent: August 10, 2021Assignee: FUJIFILM Business Innovation Corp.Inventors: Yoshiyuki Tominaga, Masaaki Yamaura, Kotaro Araki, Ayumi Noguchi
