A waste liquid absorber is adapted to absorb waste liquid discharged from an outlet configured to eject ink in an accommodated state when the waste liquid absorber is accommodated in an accommodation portion. The waste liquid absorber includes a first portion and a second portion having different densities in a thickness direction of a single piece of the waste liquid absorber, and the first portion has higher density than the second portion. Each of the first portion and the second portion includes a fiber and solid flame retardant powders. The fiber of the first portion is formed of material that is the same as material of which the fiber of the second portion is formed.

Waste liquid absorber, waste liquid tank, and liquid droplet ejecting device

To provide a waste ink absorber having excellent permeability and retention, a waste ink absorber absorbing waste ink discharged from a head for injecting ink is provided with a first portion and a second portion having different densities, and the first portion has higher density than the second portion.

Waste ink absorber, waste ink tank, and liquid droplet ejecting device

A waste ink absorber is for absorbing waste ink discharged from a head for ejecting ink. In a side cross-sectional view of the waste ink absorber, a portion low in density and a portion high in density as compared with the portion low in density are laid alternately and obliquely such that the portion low in density and the portion high in density appear alternately on each surface of the waste ink absorber.

To provide a waste ink absorber excellent in permeability and retaining performance, a waste ink absorber to be mounted in a waste ink tank to absorb waste ink discharged from a head for ejecting ink, includes, in a state of a single piece of the waste ink absorber not mounted in the waste ink tank, a portion low in density and a portion higher in density as compared with the portion low in density in a direction along a plane surface having a largest surface area.

To provide a waste ink absorber excellent in permeability and retention performance, it is directed to a waste ink absorber for absorbing waste ink discharged from a head for ejecting ink. In a side cross-sectional view of the waste ink absorber, a portion low in density and a portion higher in density as compared with the portion low in density are laid alternately obliquely.

To provide a waste ink absorber having excellent permeability and retention performance, in a waste ink absorber to absorb waste ink discharged from a head for ejecting ink, maximum parts where the density is locally high and a low density portion where the density is lower than the high density portion are provided in a single piece of the waste ink absorber.

A waste ink absorber for absorbing waste ink discharged from a head for ejecting ink includes layers the same in density and different in flame retardant content ratio, which are stacked.

An image forming apparatus includes: an image carrier; a transfer roller that has a gripping member that grips a transfer medium; and a transfer medium transport section that has a transfer medium transport surface that sucks the transfer medium upward in a vertical direction and a contact member that contact with the transfer medium, wherein a first position where the transfer medium starts to be sucked, a second position where the transfer medium is released from the gripping member, and a third position where the transfer medium is separated from the image carrier are disposed at positions having the relationship of L&#x3c;L+L, wherein L is the distance between the third position and the first position, Lis the distance between the third position and the second position, and Lis the distance between the second position and the first position.

Image forming apparatus and image forming method

A development apparatus includes an anilox roller for supplying liquid developer to a development roller and a supply roller arranged in a developer container and held in contact with the anilox roller to supply the liquid developer to the anilox roller. An AC voltage is applied to the supply roller, and a bias voltage is applied to the development roller. Liquid developer contained in grooves of undulations of an anilox pattern formed on a surface of the anilox roller is applied to the development roller.

Development apparatus and image forming apparatus using the same

There is provided a development system comprising a developer carrier member that carries a developer, a developer supply roller that supplies the developer carrier member with the developer, a developer container that stores the developer, a toner compression roller that contacts with the developer carrier member and presses toner against the developer carrier member, the toner included in the developer and a density sensing unit that senses a density of the toner in the developer in the developer container. A condition for the toner compression roller is changed depending on the density of the toner in the developer in the developer container or depending on a type of a recording medium.

Image forming apparatus and method that changes toner compression roller condition depending on toner density or recording medium type

A wire bar is formed by winding a wire, which comprises a first flat portion formed along an overall longitudinal length, around a peripheral surface of a metal core such that the peripheral surface of the metal core and the first flat portion tightly contact with each other. Since this increases the area size of a contact portion where the wire and the metal core contact each other, it is possible to increase the force of static friction which fixes the wire to the metal core. Fixing of the wound wire to the metal core by the strong force of static friction effectively prevents the wound wire from getting deviated.

Wire bar, method of manufacturing wire bar, and image forming apparatus

The present invention provides a toner which can properly ensure elasticity and viscosity after transiting fixing nip, can improve surface smoothness of the fixing surface, fixing strength of a toner and transparency, low temperature fixing ability, and can prevent fattening of characters by using dynamic viscoelastic characteristics more conformable for actual toner behavior in fixation by heating, further provides an image-forming apparatus capable of forming a high quality image while enhancing low temperature fixing ability, realizing oil-less fixation and preventing offset of a toner.
