Estimating the term…
An air flow is generated in a space adjacent to the toner control member 3, when an image is not being formed, and also a cleaning electric field for moving the toner away from the toner control member 3 is generated in the same space. For instance, a slit 2a is formed in an outer peripheral section of a cylindrical and rotatable counter electrode member 2, and an air flow generating source 10 such as a fan is connected to the counter electrode member 2. A convex cleaning electrode 11 is formed around the slit 2a of the counter electrode member 2, and a voltage for forming a cleaning electric field is applied from the power supply source for cleaning 8 to this cleaning electrode 11.
An image forming method for forming an image on an image forming medium by making an electrically charged powder as an image forming substance jet via a powder control member having holes thereon through which said powder can pass towards the recording medium and selectively allowing passage of the powder flying towards said recording medium through the holes according to image information;
An image forming apparatus for forming an image on an image forming medium by making an electrically charged powder as an image forming substance jet via a powder control member having holes thereon through which said powder can pass towards the recording medium and selectively allowing passage of the powder flying towards said recording medium through the holes according to image information;
A cleaning device for removing electrically charged powders adhered to a body, comprising:
An image forming apparatus comprising a plurality units of image forming section each forming an image on an image forming medium by making an electrically charged powder as an image forming substance jet via a powder control member having powder passage holes towards the recording medium and selectively allowing passage of said powder flying towards said recording medium through said powder passage hole according to image information, and also having a belt member which can move along image forming positions on the image forming section and a belt driving unit, for driving said belt member;
An image forming apparatus comprising a plurality units of image forming sections each comprising a powder carrier for carrying thereon an electrically charged powder as an image forming substance, a counter electrode member arranged at a position opposing to said powder carrier, a jet electric field forming unit for forming a jet electric field for making the powder on said powder carrier jet towards said counter electrode member, a powder control member having powder passage holes for controlling jet of the powder from said powder carrier to said counter electrode member between said powder carrier and said counter electrode member and also having a control electrode in a space around each of said powder passage holes, said image forming apparatus also having a belt member which can move along the image forming positions in each image forming section, a belt driving unit for driving said belt member;
