Abstract: A heating device includes a resistance heating element that includes an electrode portion to which electric power is supplied and is rotatable, a connector that is attached to the resistance heating element, includes a contact terminal rotatable together with the resistance heating element, and supplies electric power to the resistance heating element through the contact terminal, and a pressing structure that presses the contact terminal against the electrode portion after the connector is attached to the resistance heating element.

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.

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.

Abstract: A fixing device includes: a fixing member to be used in fixing an image on a recording medium; a rotatable member pressed against the fixing member while being allowed to rotate, the rotatable member cooperating with the fixing member in such a manner as to form a pressurization part where the recording medium is to be pressurized; and a transmission unit configured to transmit a rotational driving force to the rotatable member. The rotatable member is movable in a toward-and-away direction relative to the fixing member. The toward-and-away direction of the rotatable member is different from a direction in which the driving force transmitted by the transmission unit acts.

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.
