摘要： A developing apparatus using a liquid developer and a developing head located to face a path along which a recording medium carrying, for example, an electrostatic latent image thereon is transported. A groove is formed in the surface of the head that faces the transport path. After development, the liquid remaining at the corner defined by the upper inner portion of the groove and the medium is rapidly collected to allow a minimum of smear to occur on the part of the medium which will be transported later. When the transport of the medium should be interrupted during development due to, for example, a jam, the liquid in the groove is collected to prevent a great amount of liquid which would smear a drive roller and other transport members from being transferred from the head to the medium.

摘要： Image forming equipment for performing a predetermined image forming operation by use of a stepwise drive source such as a stepping motor or pulse motor. Either one of a recording medium and a record head is driven by a pulse motor, and whether or not it has reached a predetermined position is determined. While such a decision as to the position of the recording medium or the record head is under way, the displacement per step is changed over to a displacement per step smaller than a displacement to be effected while the predetermined image forming operation is under way.

摘要： An image forming apparatus for electrostatically transferring a latent image formed on a photoconductive drum or similar image carrier to a recording medium held by a clamp drum or similar medium conveying member. The clamp drum has a cylinder or base made of aluminum, a conductive rubber layer covering the cylinder, and an overcoat layer covering the rubber layer and higher in electric resistance than the rubber layer. A bias voltage for latent image transfer is applied while the rubber layer is connected to ground. The photoconductive drum and clamp drum are pressed against each other by a predetermined force, the former following the rotation of the latter. The photoconductive drum is provided with a photoconductor having a great electrostatic capacity, thereby preventing the effective transfer voltage at the time of image transfer from increasing.

摘要： A flat solid discharging device applicable to an electrophotographic copier, facsimile apparatus and other electrostatic recording apparatuses for charging or discharging a photoconductive element. The device includes a dielectric element, a first and a second electrode juxtaposed to each other through the dielectric element, and a power source for applying an ac voltage across the first and second electrode to produce ions in the vicinity of the two electrodes. The first electrode has a hairline configuration and extends along the length of the device. The second electrode is constituted by a plurality of comblike conductive strips each of which extends crosswise relative to the first electrode through the dielectric. By adequately selecting the pitch of the conductive strips and the distance between the second electrode and the photoconductive element, irregularity in charging which corresponds to the pitch of the conductive strips is made negligible. The second electrode is divided into a plurality of segments in order to selectively charge the photoconductive element over different charging areas as desired.

摘要： A wet-type image forming apparatus produces a high-quality toner image by condensing a toner image on a photosensitive drum and adhering the toner image onto the photosensitive drum without contacting a liquid carrier applied on the photosensitive drum. The photosensitive drum carries a latent image formed thereon. The toner image is formed by developing the latent image by using a developing liquid including the liquid carrier and toner dispersed in the liquid carrier. An excessive amount of liquid carrier on the photosensitive drum is removed after the toner image is formed. An electric field is formed which causes a current to flow between an electrically conductive member and the photosensitive drum. An air gap is formed between the liquid carrier on the photosensitive drum and the electrically conductive member so that the current flows through the gap, the liquid carrier and the toner image. The toner image on the photosensitive drum is transferred to a transfer material after the toner image passes an area in which the electric field is generated.

摘要： Deterioration of a dry developing substance causes toner particles to be so strongly adhered to carrier particles that they cannot be readily separated therefrom. The present apparatus comprises means for applying a predetermined electrostatic or air suction force to the developer to readily remove toner therefrom except for spent toner particles strongly adhered to the carrier particles. The toner density, or the ratio of toner to carrier particles, is then measured electromagnetically or optically and compared to a reference value. The developer deterioration determines what proportion of toner will be removed from the developer by said force and thereby the subsequently sensed toner density. The higher the sensed toner density, the greater the degree of deterioration.
