  • Publication number: 20240111242
    Abstract: An image forming apparatus includes a drum unit, a developing unit, a developing roller bearing, a guide portion, and an urging portion. The drum unit includes a photosensitive drum. The developing unit includes a developing roller. The developing roller bearing supports the developing roller and can move radially and rotate axially with respect to the developing unit. The guide portion is formed in the drum unit and guides the developing roller bearing in directions toward and away from the photosensitive drum. The urging portion urges the developing unit in such a direction that it presses the developing roller against the photosensitive drum. The developing unit includes a restriction portion that restricts the rotation of the developing roller bearing with respect to the developing unit within a predetermined range.

  • Patent number: 7916549
    Abstract: In a semiconductor device, a self-test circuit includes a write part for writing data in a given address of a special region of a nonvolatile memory; a read part for reading the written data from the given address; a verify part for determining whether or not the written data accords with the read data; and a decision part for determining soundness of the nonvolatile memory on the basis of a result of determination made by the verify part. In the case where the written data accords with the read data, the decision part determines that the nonvolatile memory is sound, and in the case where the data do not accord with each other, it determines that the nonvolatile memory is unsound.
