摘要： In an image forming apparatus of the present invention, a resistant layer 13 of each writing electrode 3b is formed substantially in a semi-circular convex shape projecting upwardly. Therefore, the top of the resistant layer 13 is a spherical surface so that the resistant layer 13 is in point contact with the charged layer 2d of the latent image carrier 2. Because of point contacts, foreign matters adhering to the surface of the latent image carrier 2 are easily allowed to pass, thereby preventing the occurrence of filming on the surface of the latent image carrier 2.

摘要： An image forming apparatus of the present invention comprises: a latent image carrier; and a developing means for charging a toner into a negative polarity by triboelectric charging, for converting an electrostatic latent image on said latent image carrier to a visible image with said toner and is characterized in that (1) the work function (nullt) of said toner is set to be larger than the work function (nullOPC) of the surface of said latent image carrier, or (2) in case that the apparatus is of a type transferring the visible image to an intermediate transfer medium, the apparatus is characterized in that the work function (nullt) of said toner is set to be larger than the work function (nullTM) of the surface of said intermediate transfer medium or (3) the work function (nullOPC) of the surface of said latent image carrier, the work function (nullt) of said toner, and the work function (nullTM) of the surface of said intermediate transfer medium are set to satisfy a relation nullt>nullOPC>nullTM. According to this apparatus, during development, the amount of fog can be reduced and the transfer efficiency can be improved. Since the transfer efficiency from the latent image carrier to the intermediate transfer medium is improved, thereby reducing the consumption of the toner, reducing the cleaning toner amount. Therefore, reduction in running cost and reduction in size of the cleaning toner container can be achieved.

摘要： In a color image forming apparatus, a looped belt member is stretched and circulated by at least a drive roller and a driven roller so as to have a tensed side and a slack side. Each of plural image supporting members supports a single color toner image thereon, and abuts onto the tensed side of the belt member to define a transferring position at which the toner image is transferred onto either the belt member or a recording medium held by the belt member, while being rotated. A circumferential velocity of each image supporting member is determined so as to be lower than a circulation velocity of the belt member. Further, a circumferential velocity of an image supporting member which is further from the driving roller may be lower than a circumferential velocity of an image supporting member which is closer to the driving roller.

摘要： A recording medium having a toner image formed thereon is moved to pass through a press contact portion between an endless belt being heated and an pressure roller pressed against the endless belt. When passing through the press contact portion, the toner image is fused and permanently affixed onto the recording medium. An oil application width O of an oil application roller is shorter than belt width B of the endless belt, and a maximum passing width P of a recording medium that may be supplied for the image formation, but is longer than a maximum image-forming width I within which an image may be formed on the recording medium.

摘要： In an image forming apparatus of the present invention, a plurality of writing electrodes 3b are supported by an elastic and flexible substrate 3a such that the writing electrodes are aligned in a plurality of rows each extending in the axial direction of the latent image carrier (in the main scanning direction). The writing electrodes 3b are each formed in, for example, a triangle and are arranged in such a manner that the orientations of the triangles of the writing electrodes are alternately inverted. In this case, one end of the triangle base of a writing electrode is overlapped with one end of the triangle base of a next writing electrode 3b, as seen in the direction perpendicular to the axial direction of the latent image carrier 2 (the rotational direction of the latent image carrier 2; the feeding direction). Therefore, this design prevents occurrence of image defect due to linear stains and allows foreign matters adhering to the surface of the latent image carrier 2 to pass through spaces between the adjacent writing electrodes 3b.
