  • Publication number: 20240152079
    Abstract: A heating device includes a first rotating body, a heater, a temperature detection element, and a heater holder. The heater includes a heating element and a substrate on which the heating element is located. The temperature detection element is located on a second surface of the substrate opposite to a first surface of the substrate in a thickness direction of the substrate. The heater holder includes a reservoir portion configured to reserve grease to be supplied to between the first rotating body and the heater in a longitudinal direction of a longer side of the first surface of the substrate. A length of an area in the thickness direction of the reservoir portion overlapping an area where the temperature detection element is located is greater than a length of an area in the thickness direction of the reservoir portion not overlapping the area where the temperature detection element is located.

  • Patent number: 11927894
    Abstract: An image forming apparatus includes first and second image bearing members and first and second developing members. The controller controls to execute first and second controls based on image information in a case that the first developing member is separated from the first image bearing member when an operation in which the image is sequentially transferred to a transferred member from the first and second image bearing members is terminated. The first developing member is started to separate from the first image bearing member in the first control after an end of an image forming area on the first image bearing member in a moving direction passes through the first transfer position, and in the second control after the end of the image forming area on the first image bearing member in the moving direction passes through the developing position and before the end of the image forming area reaches the first transfer position.

  • Publication number: 20240077816
    Abstract: A fixing apparatus includes an endless first rotary member, a heating element, a second rotary member configured to form a nip portion, and a nip member configured to receive radiant heat from the heating element and heat the nip portion. The nip member includes a main-body portion that contains aluminum or aluminum alloy and a protective layer that includes an oxide film formed on a surface of the main-body portion. The main-body portion contains a heat receiving surface that faces the heating element and receives radiant heat from the heating element, and a rubbed surface that is rubbed against the inner circumferential surface of the first rotary member. The protective layer contains coloring agent that causes an emissivity of the heat receiving surface and the rubbed surface to be higher than an emissivity of a natural color oxide film.

  • Publication number: 20130050645
    Abstract: According to an embodiment, an attachment is attached to a main body part and has multiple bright points arranged in a ring. A calculation part calculates a first astigmatic axis angle based on an image obtained by using an imaging optical system to photograph the patient's eye while the multiple bright points are projected thereto. A storage stores the calculated first astigmatic axis angle and/or a second astigmatic axis angle measured before surgery. A mechanism changes the orientation of the main body part. A first input part inputs orientation information indicating the orientation of the main body part. A correction part corrects the first astigmatic axis angle and/or the second astigmatic axis angle based on the input orientation information. A display part displays the corrected first astigmatic axis angle and/or the corrected second astigmatic axis angle.
