摘要： A developing unit includable in a process cartridge and in an image forming apparatus includes a developer bearing member including a magnetic field generator and a nonmagnetic hollow member, a developer container, an agitation/conveyance member, and a developer regulating member. The magnetic field generator has first and second magnetic poles to generate respective magnetic forces for removing the developer from the developer bearing member after the developer passes the development region. A developer-releasing region releases the developer from the developer bearing member using a release force. The developer is disposed higher than a surface of the developer in the developer storing chamber. A component of a magnetic flux density of the magnetic field generated by the magnetic field generator in a direction normal to the developer-releasing region is directed to a same direction as the first and second magnetic poles across the developer-releasing region without forming a local maximum point.

摘要： An image forming apparatus includes an image carrier removably installed in the apparatus to carry an image; a transfer member contacting with the image carrier to transfer the image onto the transfer member or a recording medium; a contact and separation mechanism causing the transfer member to contact with or separate from the image carrier; and a removable unit removably installed in the apparatus from the same direction as an installation direction of the image carrier to be disposed proximal of the image carrier and the transfer member in the installation direction, and at least partially overlapping the image carrier and the transfer member as viewed in the installation direction. The removable unit interferes with the contact and separation mechanism and is prevented from being installed in the apparatus, when the transfer member is separated from the image carrier by the contact and separation mechanism.

摘要： A cleaning device includes a brush roller configured to contact an image bearer while rotating to remove toner adhering to an image bearer, a bias applying device configured to apply a bias to the brush roller, and control circuitry configured to causes the bias applying device to apply a first bias in a first period from when the brush roller is new to when a cumulative travel distance or a cumulative rotation time of the brush roller reaches a predetermined value, and to apply a second bias in a second period after the first period. The first bias sends a first current through the brush roller, and the second bias sends a second current through the brush roller. The absolute value of the first current is smaller than the absolute value of the second current.
