摘要:
An image forming apparatus includes a photoconductor on which an electrostatic latent image is formed by irradiation of the photoconductor with light, a charger, a developing device, a transfer device, a charge removal execution determiner, and a power supply controller. The charger receives a superimposed voltage of a DC voltage and an AC voltage to charge the photoconductor. The developing device develops the electrostatic latent image on the photoconductor into a toner image. The transfer device transfers the developed toner image to a recording medium. The charge removal execution determiner issues a charge removal command when a flow of electric charge from the transfer device into the photoconductor has occurred in an image forming outputting operation. The power supply controller applies only the AC voltage to the charger for a predetermined period in a state in which the photoconductor is rotated, when the charge removal command is issued.

A development device can include a developer containing part containing developer, a carrier to carry developer that is supplied from the developer containing part to a development range, a partition dividing the developer containing part into a supply part and a circulation part beneath the supply part to collect developer from the carrier, a first transport member in the supply part of the developer containing part to supply developer from the supply part to the carrier, and a second transport member in the circulation part to transport developer in the circulation part in an axial direction of the carrier. The device can also include a removable seal member, which seals a supplied-developer and/or a collected-developer communicating area.
摘要:
A development device includes a development casing, a developer bearer, a first developer conveyance member to supply developer to the developer bearer, a second developer conveyance member to transport developer axially, and a partition dividing an interior of the development casing into a supply channel and a collecting channel via which developer received from a downstream end portion of the supply channel is forwarded to an upstream end portion of the supply channel. The supply channel includes a conveyance area and a buffer area disposed adjacent to the conveyance area in a direction perpendicular to an axial direction to temporarily retain developer and midway in the developer conveyance direction inside the supply channel, and an upstream end face defining an upstream end of the buffer area is inclined relative to the axial direction to draw away from the conveyance area downstream in the developer conveyance direction.

摘要:
A development device includes a developer container internally divided by a partition into a supply path and a recovery path, a developer bearing member, a supply conveyance member to apply force to convey developer to a developer retaining space through the supply path, the developer retaining space retaining the developer to be conveyed by the developer bearing member, a recovery conveyance member, a communication pathway provided between the supply path and the developer retaining space, the communication pathway passing the developer from the supply path to the developer retaining space, and a developer softening member to soften the developer that is present above the partition, provided at least one of at a position in the communication pathway and at a position close to the communication pathway.
摘要:
A development device includes a developer bearer to carry by rotation two-component developer to a development range to develop a latent image formed on a latent image bearer, a magnetic field generator disposed inside the developer bearer, a developer regulator for adjusting an amount of the developer on the developer bearer, positioned upstream from the development range in a rotational direction of the developer bearer and facing the developer bearer across a regulation gap, a supply compartment from which the developer is supplied by a developer agitator to the developer bearer, a collection compartment, a pre-regulation portion adjacent to and upstream from the developer regulator in the rotational direction of the developer bearer, and a developer mobility adjuster that makes mobility of the developer in the pre-regulation portion higher on an upstream side in a developer conveyance direction in the supply compartment.
摘要:
A surface moving body includes an endless surface that is capable of making an endless movement. A surface-moving-body drive mechanism includes a driving source of a driving force for moving the surface moving body and a drive transmission mechanism for transmitting the driving force from the driving source to the surface moving body. At least a part of the surface-moving-body drive mechanism is arranged in a surface-moving-body occupying space surrounded by two surfaces defined by ends of the endless surface in a width direction orthogonal to a surface moving direction of the endless surface and the endless surface.
摘要:
A housing of a rotation type camera apparatus has a standing installation surface for standing installation and a wall-mounting installation surface for wall-mounting installation. The housing is also provided with a dome type cover composing a shooting window facing in a slanting direction with respect to a horizontal direction in a standing-mounting position and in a wall-mounting position. A camera is provided so as to be able to shoot outside from the shooting window. A camera rotation device is accommodated in the dome and has a pan rotation axis based on the horizontal direction. The shooting window faces in an appropriate direction in both the standing-mounting position and the wall-mounting position. Since the pan rotation axis is set based on the horizontal direction, a viewer's eyes do not run up and down so much during the pan rotation.
