In a standby state capable of forming an image, a period of a drive pulse of a heater in a fixing unit is made longer than that of the drive pulse in an image formation state to decrease the number of ON/OFF times of a fixing heater, thereby decreasing a brightness flicker in an illumination equipment which is connected to a power supply system identical with that of an image formation apparatus for ON/OFF controlling the heater to control temperature of the fixing unit to be at a target temperature.

Flicker suppression device in electronic equipment

A fixing apparatus includes a fixing member and a heating unit. The fixing member forms a nip to convey a recording member which has an unfixed toner thereon. The toner on the recording medium is spherical. The heating unit is provided upstream of the nip in the moving direction of the recording medium, and does not come into contact with the recording medium. The fixing apparatus may include a control means for controlling the heat given from the heating unit to the recording medium.

Fixing apparatus for controlling distance between heating means and guide member

The present invention relates to an image heating apparatus, in which an end of a first magnetic portion and an end of a second magnetic portion are present within a width along a recording material moving direction of a nip, and a width of a gap along a recording material moving direction is different with respect to a direction which is orthogonal to the recording material moving direction.

Image heating apparatus

A cleaning apparatus for cleaning a heat fixing member is disclosed which includes a cleaning member to be brought into contact with a surface of a heat fixing member, and a wax b held on the cleaning member. Also, a heat fixing method and an image forming method are disclosed which use the cleaning apparatus.

Cleaning apparatus for cleaning heat fixing member, heat fixing method

The present invention provides an image forming method including the steps of: forming an electrostatic latent image on a latent image holding member; developing the electrostatic latent image by using a color toner to form a toner image; transferring the toner image onto a recording material; and fixing the toner image to the recording material by a heat fixing device including a heating member in contact with the toner image. In the method, the color toner contains at least a binder resin, a colorant and wax, the wax having a molecular weight distribution measured by GPC, which has a ratio of the weight average molecular weight (Mw) to the number average molecular weight (Mn) of 1.45 or less, and a solubility parameter (SP value) of 8.4 to 10.5. If the contact angles between the wax and the heating member at 100.degree. C. and 200.degree. C. are A and B, respectively, the contact angles A and B satisfy the following relations:

A fixing rotatable member for use in an image forming apparatus such as a copying apparatus or a laser beam printer is disclosed. The fixing rotatable member includes a base member and an elastic layer provided on the surface thereof. The elastic layer is addition type silicone rubber in which resin-like polyorganosiloxane and 0.1 to 2 percent by weight of inorganic fine powder are mixed.

Rotatable member for fixing in which inorganic filler is contained in

A cleaning member carrying porous particles for absorbing a parting agent is used in an electrophotographic apparatus having a fixation unit in which a developer image transferred to a transfer member is fixed by a fixation rotary member to which the parting agent is applied, and means for forming an image on two surfaces of the transfer member.

Electrophotographic apparatus cleaning member and electrophotographic

The present invention relates to cleaning fiber provided for a cleaning unit of an image forming apparatus such as an electrostatic copying machine or an electrostatic printer using an electrostatic process, the cleaning fiber being capable of quickly removing transferred oil which causes oil fog to be generated. The cleaning fiber according to the present invention contains inorganic porous particles dispersed therein.
