摘要:
An image forming apparatus includes an image bearing member, a latent image writing device that emits a plurality of laser beams, two adjacent laser beams of the plurality of laser beams partially overlapping in a sub-scanning direction, respectively, and forming a reference latent image on a surface of the image bearing member by performing repeated scanning of each laser beam on the surface of the image bearing member, a developing device that develops the reference latent image with toner into a reference toner image, and a detecting device that detects the density of the reference toner image. The quantity of light of each laser beam forming a subsequent latent image is adjusted according to the density of the reference toner image detected by the detecting device.
摘要:
An image forming apparatus capable of collecting toner left on an image carrier after image transfer during an electrophotographic process, and returning the toner to a developing unit for reuse in the form of an air-toner mixture is disclosed. A toner conveying device includes a screw pump and a hopper portion positioned upstream of the screw pump in the intended direction of toner conveyance. When the collected toner accumulating in the hopper portion reaches a preselected amount, the toner conveying device is caused to start and stop operating at a specific timing.

A toner recycling device of an electrophotographic image forming apparatus conveys collected used toner to a developing device of the image forming apparatus. The toner recycling device includes a powder conveying pump that is driven to convey the collected used toner to the developing device of the image forming apparatus when an integrated value of predetermined numerical values, each based on a number of picture elements of an image to be formed, is equal to or greater than a constant value, and an adding device that adds a predetermined constant value to the integrated value when driving of an image bearing member of the image forming apparatus is detected.
摘要:
An image transferring device for transferring a toner image from an image carrier to a recording medium includes a belt passed over a plurality of rotary bodies for supporting and conveying the recording medium and a cleaning member for cleaning the surface of the belt in contact therewith. A dielectric layer forms the surface of the cleaning member. An image forming apparatus including the above image transferring device is also disclosed.
摘要:
A transfer device for transferring a toner image formed on an image carrier onto a transfer material conveyed on a transfer belt. The transfer device includes a cleaning member having a dielectric surface layer for cleaning a surface of the transfer belt, and a bias application unit for applying to the cleaning member a cleaning bias having an opposite polarity to an electric charge polarity of a toner forming the toner image. Further, specific characteristic values of the dielectric surface layer are set to achieve a higher than predetermined cleaning level, such as setting a volume resistivity of the dielectric surface layer is set to 1E4 ohms/square or more.

A mobile image forming apparatus includes a body, a recording device supported by the body and configured to form an image on a recording medium, a roller provided to the body and configured to rotate on the recording medium while the body is moved in a scanning direction for image formation. The mobile image forming apparatus further includes a switching device configured to switch a state of the mobile image forming apparatus during image formation between a roller contact state in which the roller is in contact with the recording medium and a roller contactless state in which the roller is contactless with the recording medium.

A mount board tray is provided to hold multiple mount boards at different heights above and below the mount board tray. The mount board tray holds a topmost mount board placed at the topmost position among the multiple mount boards held by the mount board tray from below the topmost mount board. The mount board tray also holds a bottommost mount board placed at the bottommost position among the multiple mount boards from above the bottommost mount board at the same time.

In exemplary implementations of this invention, a shape controller controls the shape of a bladder as the bladder inflates. The shape controller includes a first set of regions and a second set of regions. The second set of regions is more flexible than the first set of regions. The shape controller is embedded within, or adjacent to, a wall of the bladder. When the bladder is inflated, the overall shape of the bladder bends in areas adjacent to the more flexible regions of the shape controller. For example, the shape controller may comprise paper and the more flexible regions may comprise creases in the paper. Or, for example, the more flexible regions may comprise notches or indentations. In some implementations of this invention, a multi-state shape display changes shape as it inflates, with additional bumps forming as pressure in the display increases.

In exemplary implementations of this invention, an array of linear actuators can be used to form a segmented surface. The surface can resemble a low relief sculpture. A user may control the shape of the surface by direct touch manipulation or by making freehand gestures at a distance from the surface. For example, the freehand gestures may comprise input instructions for selecting, translating, and rotating the shape of an object. A projector may augment the rendered shapes by projecting graphics on the surface.
