摘要:
A medium supplying apparatus includes a separation mechanism that separates one medium at a time from a plurality of sheet-shaped media stacked in a loading rack and transports the medium, an irradiation unit that emits light onto a surface of the medium, and a light receiving unit that receives reflected light that is acquired by allowing the light emitted by the irradiation unit to be reflected from the surface and detects a reflected light intensity that is an intensity of the reflected light. The separating force of the separation mechanism that is used for separating a next medium is controlled based on the reflected light intensity detected by the light receiving unit.
摘要:
A cleaning apparatus for a liquid-development electrophotographic apparatus in which, after a toner image formed on a surface of an intermediate transfer member by use of a liquid developer is transferred to a printing medium, the liquid developer remaining on the intermediate transfer is removed and collected. The cleaning apparatus includes a cleaning-liquid application device for applying a cleaning liquid to the intermediate transfer member which has transferred an image to the printing medium; a bias voltage application device for applying a bias voltage opposite in polarity to charged toner particles of the developer to the intermediate transfer member; and a collection device for removing the cleaning liquid which has been applied to and the residual developer which remains on the intermediate transfer member from the intermediate transfer member without transfer of an image to the printing medium, and collecting the removed cleaning liquid and residual developer.
摘要:
A friction-coefficient estimating device is configured to estimate friction coefficient of the surface of a medium in a form of a sheet by irradiating a light on the surface and by detecting specularly-reflected light component of a reflected light and a diffusely-reflected light intensity. The friction-coefficient estimating device comprises an irradiating unit including a first irradiating unit and a second irradiating unit, a specularly-reflected light receiving unit including a first specularly-reflected light receiving unit that receives a first specularly-reflected light component of a reflected light and detects a first specularly-reflected light intensity and a second specularly-reflected light receiving unit that receives a second specularly-reflected light component of a reflected light and detects a second specularly-reflected light intensity, and a diffusely-reflected light receiving unit that receives a diffusely-reflected light component of a reflected light and detects a diffusely-reflected light intensity, and a control unit that estimates a friction coefficient of the surface based on a first reflected-light intensity coefficient and a second reflected-light intensity coefficient.
