  • Publication number: 20240100857
    Abstract: A heat generating member includes: a hollow cylindrical part that is rotatable about a rotation axis and extends in an axial direction; a first heat generating component provided on an inner surface of the cylindrical part and configured to generate heat when energized; a first connecting component provided on an inner side relative to the cylindrical part and electrically connected to the first heat generating component, the first connecting component being rotatable together with the cylindrical part; a second connecting component provided on a further inner side relative to the cylindrical part than the first connecting component and electrically connected to a power source, the second connecting component being rotatable relative to the cylindrical part; a rotary supporting component that electrically connects the first connecting component and the second connecting component to each other and supports the first connecting component while allowing the first connecting component to rotate relative to the s

  • Publication number: 20240094665
    Abstract: A belt unit includes: a belt-shaped member being endless; and a support member that supports the belt-shaped member and rotates, the support member having a rotating shaft that tilts in: a tilt direction having a component in a first direction intersecting a bisector of a central angle of a wrapping range where the belt-shaped member is wrapped around the support member and a component in a second direction where the belt-shaped member elongates and contracts; and a direction where extent of shifting of the belt-shaped member to one side in the width direction of the belt-shaped member is reduced.

  • Patent number: 11092908
    Abstract: 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.

  • Patent number: 11086250
    Abstract: 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.

  • Patent number: 11029625
    Abstract: An image forming apparatus includes: an image carrier configured to carry an image; a transfer unit configured to transfer the image to a medium; and a cleaner configured to remove deposits on a surface of the image carrier after passing through a position of the transfer unit, in which when a type of a medium to be used is a first medium, the cleaner improves an ability to remove the deposits from the image carrier as compared with a case where the medium to be used is a second medium having a lower transfer sensitivity than the first medium.
