摘要:
A method of and an apparatus for recording an image on a recording medium. A heat-sensitive sheet having a light-transmissive base sheet provided with a heat-fusible supercooled substance layer is made to abut a copy original such that the heat-fusible supercooled substance layer faces the original image to be copied while flashlight is projected onto the base sheet of the heat-sensitive sheet. Thus, the image portion of the copy original to be copied absorbs the light transmitted through the heat-sensitive sheet and thereby generates heat so that an adhesive area containing a pattern corresponding to the original image is formed on the supercooled substance layer. After the heat-sensitive sheet has been removed from the copy original, such an adhesive area is transferred to the recording medium owing to the adhesiveness of the adhesive area.

A method of charging or discharging a member including the steps of, opposing to a member to be acted, a discharging member having a dielectric member, an inducing electrode and a discharging electrode sandwiching the dielectric member so that the discharging electrode faces the member to be acted, applying an alternative voltage between the inducing electrode and the discharging electrode to produce a surface discharge on a surface of the dielectric member at the discharging electrode side, moving the member to be acted relative to the discharging electrode to charge or discharge the member to be acted by the thus formed surface discharge, ceasing the production of the surface discharge by attenuating both of positive and negative, at the discharging electrode relative to the inducing electrode, components of the alternating voltage at least down to a discharge stopping voltage and then rendering the voltage zero.

An image recording apparatus includes a rotatable transfer member and a plurality of latent image bearing members which are in rolling press-contact with the transfer member at different positions. Around the latent image bearing members, are provided latent image forming devices and devices for developing the latent image. The developed images formed on the respective latent image bearing members are transferred by pressure onto a recording material or onto the transfer member at the respective nips formed between the transfer member and one of the latent image bearing members. With this apparatus, duplex image recording, overprint or superimposing recording, and/or high speed recording can be accomplished.

An image recording and/or reproducing apparatus including a recording unit having a recording driving mechanism for recording a plurality of images in the form of electrostatic pattern on different regions of a photosensitive member, a reading unit having a beam source and capable of scanning the photosensitive member by an electron beam so as to convert the recorded pattern into electric signals, and a connecting member for connecting the recording unit and the reading unit without causing any change in the states of these units. This apparatus makes it possible to record and/or to reproduce images with a high image quality. The connecting member includes a container accommodating the recording unit and the reading unit. Alternatively, the connecting member is adapted to keep a portion of the recoding unit and a portion of the reading unit in close contact with each other.

This specification discloses a method of toner transfer development in which a low frequency alternating electrical bias is applied to the space between a latent image bearing member and a developer carrying member to develop the latent image on the latent image bearing member, and an apparatus for carrying out the same method. This bias has a first process in which reciprocal movement of developer particles is effected also between the non-image area of the latent image bearing member and the developer carrying member, and a second process in which the intensity of the bias is adjusted so that one-sided movement of developer particles from the developer carrying member to the image area and one-sided movement of developer particles from the non-image area to the developer carrying member may take place.

摘要:
An image formation apparatus having an image formation station for causing a recording medium to bear a visualized image, a fixing station for applying high-frequency waves to thereby fix the visualized image on the recording medium and record the image, a conveyor for conveying the recording medium along a conveyance path from the image formation station until the recording medium passage through the fixing station, and a device for preventing leakage of the high-frequency waves for fixing the visualized image on the recording medium. The fixing station has a high-frequency wave applying process for fixing the visualized image on the moving recording medium. The image formation apparatus effectively utilizes the high-frequency waves for the image formation while, on the other hand, it prevents wasteful leakage of the high-freqency waves or leakage of the high-frequency waves which interferes with humans or image formation and ensures safety.
