  • Publication number: 20240323306
    Abstract: An image processing apparatus for performing masking on text-containing data includes a memory storing a program and a processor which executes the program to perform a process. The process includes receiving a selection of attributes for text strings as masking targets and displaying text strings which are identified through analysis and which correspond to the selected attributes and also displaying a preview with the text strings masked. The preview is displayed in a first area, and the text strings are displayed in a second area with information indicating the text strings are selected as masking targets. In response to receiving in the second area a user operation for deselecting one text string as a masking target, the preview in the first area displays the one text string unmasked.

    Abstract: A fixing unit includes a rotatable fixing member and a rotatable pressure applying member. The rotatable fixing member has a heat generating layer to generate heat when subject to a magnetic flux. The rotatable pressure applying member contacts the rotatable fixing member and applies pressure to the fixing member. The rotatable fixing member and the rotatable pressure applying member form a nip therebetween, to which a recording medium is passed through to fix an image on the recording medium. The rotatable fixing member includes a magnetism regulating layer deformable when subject to pressure from the rotatable pressure applying member.
