摘要:
The present invention provides a color image forming apparatus for forming a color image by superimposing a plurality of color toner images on a recording material, which can improve the quality of the toner images on the recording material during the transferring of the plural color toner images.The present invention slightly differentiates a moving speed of an electrophotographic photosensitive member as an image bearing member from a moving speed of a recording material bearing means which supports the recording material and moves with respect to the photosensitive member. Whereby, it is possible to adequately transfer the toner images onto the recording material in a superimposed fashion.

摘要:
An image forming apparatus includes first and second image bearing members; movable carrying member for carrying a transfer material through a first transfer position for electrostatically transferring a first image from the first image bearing member to the transfer material and through a second transfer position, downstream of the first transfer position with respect to a movement direction of the carrying member, for electrostatically transferring a second image from the second image bearing member onto the transfer material; wherein the apparatus is operable in a first mode wherein the images are transferred onto the transfer material both at the first and second transfer positions and in a second mode wherein no image is transferred onto the transfer material at the first transfer position, and the image is transferred onto the transfer material at the second transfer position; wherein differences in surface potentials of the transfer material immediately before and after the transfer material passes through the first transfer position in the first mode and the second transfer position in the second mode, are substantially the same.
摘要:
The present invention provides an image forming apparatus comprising an image bearing member for bearing an image thereon, and a transfer device for transferring the image from the image bearing member to a recording material at a transfer station. Wherein a limit value of electric power supplied to the transfer device is changed between a case where an imaged portion of the image bearing member is positioned at the transfer station and a case where a non-imaged portion of the image bearing member is positioned at the transfer station.

An image forming apparatus includes an image bearing member; recording material carrying member for carrying a recording material; a transfer charging member for transferring a toner image formed on the image bearing member onto the recording material carried on the recording material carrying member; a controller for controlling an electric current supplied from the transfer charger to the recording material carrying member to be a predetermined level; and potential applying device for applying a potential of the same polarity as that of the toner image to a backside of the recording material carrying member prior to transfer operation of the transfer charger.
摘要:
A method for manufacturing a wiring board for mounting an electronic component, a wiring board for mounting an electronic component, and a method for manufacturing an electronic-component-mounted wiring board are provided. A bonding material paste, which can include solder and an electric insulation material made of a resin, can be placed on chip mount terminal pads and heated to fuse the solder and soften the electric insulation material. Subsequently, the solder is solidified to form solder bumps. Further, the electric insulation material is cured on a surface of each of the solder bumps and a surface of a multilayer board around each of the solder bumps to form an electric insulation surface layer. Accordingly, when a chip is mounted to such wiring boards, the electric insulation surface layer minimizes or eliminates the connection between adjacent solder bumps during re-fusing of the solder.

Disclosed is a novel cell mass derived from a cancer tissue, which can reflect the in vivo behavior of a cancer cell correctly. Also disclosed is a process for preparing the cell mass. Specifically disclosed is a cell mass derived from a cancer tissue, which is an separated product that is isolated from a cancer tissue obtained from an individual as a mass containing at least three cancer cells or a cultured product of the separated product and which can retain a proliferation ability in vitro. The cell mass derived from a cancer tissue is produced by, for example, a preparation process comprising the steps of: treating a pulverized product of a cancer tissue removed from a living body with an enzyme; and selecting and collecting a mass containing at least three cancer cells among from an enzymatic treatment product.
