An image forming apparatus includes a recording paper conveyor, a photosensitive drum, a charger, an exposure, a developer with toner, a transfer, and a cleaner. A process unit has the photosensitive drum and the cleaner in which a blade scrapes a residual toner from the drum, a paddle rotates to move the toner from the drum, and a scraper scraping the toner carried by the arm by its free end which is disposed radially outwardly and near to a rotation locus drawn by a radially directional outer end of an arm of the paddle during a rotation of the paddle.

An image forming apparatus includes a photosensitive member, a charging device for charging the surface of the photosensitive member at a constant potential, a light beam for exposing the photosensitive member charged by the charging device to form an electrostatic latent image, a developing device for developing the electrostatic latent image by selectively sticking toner to the surface of the photosensitive member so as to correspond to the electrostatic latent image formed by the light beam, and a transfer device for transferring to recording paper the toner image formed by the developing device on the surface of the photosensitive member. The image forming apparatus is applied to a cleanerless system in which the developing device develops the toner image and simultaneously sucks and recovers residual toner remaining on the surface of the photosensitive member after transfer. The image forming apparatus further includes a scraping device that is pressed against the surface of the photosensitive member and scrapes the surface of the photosensitive member, while allowing the residual toner to pass through.

An ultrasonic probe apparatus suitable for use in stress echocardiography testing is disclosed. This ultrasonic probe apparatus comprises, an ultrasonic probe provided with a phased array transducer for transmitting and receiving ultrasonic waves; a supporting member for supporting the ultrasonic probe rotationally and pivotally; and a plurality of deformable holding legs provided on the supporting member and formed of a copper plate coated with plastic so as to be able to be easily deformed by hand and further maintain its deformed state for a long time. Therefore, the ultrasonic probe apparatus can hold the ultrasonic probe stably onto a body surface of a person to be examined for a long time by appropriately deforming or bending any of the holding legs and then attaching the legs on the body surface in such a manner that the probe is in contact with the body surface, even if the body surface has various shape and unevenness. Further, the apparatus comprises a first motor for rotating the probe and a plurality of second motors for pivotally inclining the probe, so that the contact angle and direction of the probe with respect to the body surface of the examined person in exercise can be adjustably corrected or changed by remote control when the probe is dislocated or a scanning plane is required to be changed during the stress echocardiography testing.

A recording apparatus has a development unit for depositing a toner on an electrostatic latent image on the outer surface of a photosensitive drum while attractively collecting a residual toner on the surface of the photosensitive drum, a transfer charger device for transferring the toner image to a transfer sheet, a conductive brush for uniformalizing a residual toner distribution on the photosensitive drum, after a transfer step has been carried out, and at the same time charging the surface of the photosensitive drum, and a scorotron charger located on the downstream side of the conductive brush, but on the upstream side of the exposure device, and assisting the charging of the drum surface by the conductive brush. The surface of the drum charged by the scorotron charger is exposed by a light beam to provide an electrostatic latent image thereon.
