摘要： An image recording apparatus comprises: a printer to form an image onto a recording medium; and a blank forming device to form blanks in the peripheral edge portions of the image formed on the recording medium. The blank forming device sets the blank amount in the front edge portion of the image to be smaller than the blank amount in the back edge portion or sets the blank amount of the image on the scan starting side to be smaller than the blank amount of the image on the scan end side. Even if various tolerances regarding the apparatus, copy transfer paper, conveying apparatus, and the like occur, the image is not deviated out of the paper and the toner image which is not copy transferred onto the photo sensitive drum does not remain and does not make the inside of the apparatus dirty. The effective usable region for image formation can be widened even in the two-sided mode and the multi-mode.

摘要： An electrostatic latent image developing method and a device therefor, featured in supplying one-component magnetic developer onto a developer-feeding non-magnetic bearing member to form thereon a magnetic brush of developer under the effect of a magnetic field, then bringing said magnetic brush into contact with the surface of an image-developing developer bearing member to form thereon a thin uniform layer of the developer, and bringing said thin layer to a developing position to develop an electrostatic latent image formed on a latent image bearing member. At the development the thin layer of the developer is so spaced in the developing position from the latent image bearing surface as to form a clearance therebetween, across which an AC bias electric field is applied.

摘要： An image forming apparatus includes a plurality of devices for forming an image on a rotatable medium and transferring the image onto transfer material. A detector is provided to detect the electrical condition of one of the devices during an initial turn of the rotatable medium prior to image processing. Electrical circuitry then controls the electrical condition of the one device to approach a predetermined value which value is then held for controlling the device during image formation.
