  • Patent number: 10816924
    Abstract: An image forming apparatus includes an image holding body that rotates, an image forming unit, and a return operation controller. The image forming unit includes a charger, an exposure unit, a developing unit, a transfer unit, and a cleaning unit. The return operation controller causes a clean-up step to be executed in which the image holding body is cleaned while rotating the image holding body when returning from an emergency stop. In the clean-up step, the return operation controller reduces or zeroes out a pressing force between the transfer unit and the image holding body at least until a developing operation area on a surface of the image holding body that is stopped upon the emergency stop facing toward a direction in which the developing unit operates passes through a pressing area pressed by the transfer unit.

  • Publication number: 20200096911
    Abstract: An image forming apparatus includes an image holding body that rotates, an image forming unit, and a return operation controller. The image forming unit includes a charger, an exposure unit, a developing unit, a transfer unit, and a cleaning unit, and these units sequentially operate along a rotating direction of the image holding body. The charger charges the image holding body with electricity. The exposure unit exposes the image holding body to light to form an electrostatic latent image. The developing unit includes a developing roller that feeds, while rotating, a developer including toner and a carrier to a developing area that faces the image holding body. The developing unit develops the electrostatic latent image with the toner and causes the image holding body to hold a toner image. The transfer unit transfers, while pressing a transfer-receiving body against the image holding body, the toner image on the image holding body to the transfer-receiving body.

  • Publication number: 20180113081
    Abstract: A method of increasing the yield of product semiconductor substrates includes the step of: (a) providing a monitor wafer over which a laminated film, which is similar to that over a product wafer and includes a conductor film such as an Al film, is formed; (b) etching the laminated film over the monitor wafer in a state where a photoresist film is not formed over the laminated film; and (c) irradiating the monitor wafer, placed over a stage of a foreign matter inspection apparatus, with laser light such that an etch residue (defect) is detected by its scattered light.
