  • Patent number: 11022933
    Abstract: A process cartridge includes a seal member contacting an image bearing member upstream in the rotation direction of the image bearing member from a cleaning member and allowing the developer to move from upstream in the rotation direction from the contact part between the seal member and the image bearing to downstream from the contact part while regulating movement from downstream to upstream from the contact part. The developer has surface protrusions containing an organic silicon polymer, wherein either (i) the work function of the seal member is greater than the work function of the developer when the developer has a negative charging polarity and is smaller than the work function of the developer when the developer has a positive charging polarity, or (ii) the absolute value of the difference between the work function of the seal member and the work function of the developer is within a predetermined range.

  • Patent number: 10746535
    Abstract: A component inspecting device inspects presence or absence of an abnormal state of two linear wires based on changes in the amount of received light of a first light ray and a second light ray received by a first light receiver and a second light receiver, respectively when a component is moved such that the two linear wires in the normal state block the first light ray and the second light ray in a posture wherein an arrangement direction of the two linear wires crosses optical axes of the first light ray of the first light projector and the second light ray of the second light projector. This device can detect an abnormality such as a bend or the like of linear wires by a simple configuration and a simple operation in a component having two linear wires which have axis directions parallel to each other and have different lengths.
