An end cover part is used to close an end of a cylindrical body, and transmits a driving force of a rotatable driving shaft to the cylindrical body, and the end cover part includes a cover member having a tubular portion into which the driving shaft is to be fitted, and a to-be-fitted portion which is disposed in a flange-like manner in a periphery of the tubular portion, and which is to be fitted into an end portion of the cylindrical body; and three cut surfaces which are disposed respectively on inner and outer circumferences of the tubular portion of the cover member and an outer circumference of the to-be-fitted portion, and concentrically about a common reference central axis.
摘要:
A blood pressure measurement device is characterized in that the said device is designated to arithmetically apply to the computed blood pressure value a correction value that is in accordance with the difference in atmospheric pressure between the position of the blood pressure transmitting part and the position of the heart of the subject wearing the blood pressure transmitting part as obtained from the sensor signal, on the basis of the internal pressure variation of the blood pressure transmitting part.

A charger includes: a first electrode; a second electrode that has a mesh pattern and is arranged on a side closer to a photoconductor than the first electrode; a cleaner that moves along the second electrode to clean the second electrode by a brush thereof. The second electrode has the mesh pattern successively arranged in a certain direction, and a peripheral region of the mesh pattern of the second electrode has been changed to prevent catching of the brush of the cleaner.

A color image forming apparatus, comprising: a plurality of image forming stations, each including a photo conductor on which an electrostatic latent image is formed, a developing member which develops the latent image as a visible toner image, and a single motor pinion which drives both of the photo conductor and the developing member, and a transfer belt, onto which the toner image is transferred, and which is driven by the single motor pinion of a first one of the image forming stations.
摘要:
An electrostatic latent image is formed on a rotary image carrier. A developer is provided with at least one developing roller which is separatably abutted on the image carrier at a developing position to supply toner onto the image carrier to make the latent image visible as a toner image. An intermediate transfer member is adapted to temporarily hold the toner image. A transferer applies a transfer bias to primarily transfer the toner image on the image carrier to the intermediate transfer member. A first cleaner is always abutted on the image carrier to remove toner remaining thereon. A second cleaner is separatably abutted on the intermediate transfer member to remove toner remaining thereon. The toner image includes a first toner image which is not to be transferred onto the recording medium and a second toner image which is to be secondarily transferred onto a recording medium. The second cleaner is separated from the intermediate transfer member so as to avoid the first toner image.
摘要:
A circulating intermediate transfer member contacts an image carrier at a primary transfer position at which a toner image is transferred onto the intermediate transfer member. A secondary transfer member contacts the intermediate transfer member at a secondary transfer position at which the toner image is transferred onto a recording medium. A gate roller pair nips the recording medium therebetween at a nipping position and conveys the recording medium toward the secondary transfer position. A cleaning blade retractably contacts and scrapes off toner remaining on the intermediate transfer member. A conveyance speed of the recording medium at the nipping position is faster than that at the secondary transfer position. The cleaning blade is retracted from the intermediate transfer member until a trailing end of the recording medium passes through the nipping position, when the recording medium has a stiffness greater than a prescribed level.

An image forming apparatus includes an image carrier formed with a latent image A developing device has a developing roller driven by a stepping motor. A rotary development apparatus supports the developing device on a rotating shaft to rotate to a developing position opposed to the image carrier to form an image by developing the latent image formed at the image carrier and transfers the developed image to a medium at a transferring position The developing roller is driven by the stepping motor in a region of the latent image of the image carrier and is stopped in a holding state in a region in which the latent image is not formed by a current lower than a current in driving the developing roller.
摘要:
An image forming apparatus which repeats image create/transfer processing while rotating a photosensitive member and a transfer medium in a sub scanning direction and thereafter transferring the toner image onto the transfer medium, for a plurality of toner colors which are different from each other, to thereby lay toner images in respective toner colors over each other on the transfer medium and accordingly form a color image. The apparatus corrects transfer start positions of toner image in at least one or more toner colors out of the plurality of toner colors based on a registration control amount which is necessary to correct relative registration deviations among toner images on the transfer medium.
