摘要： A hybrid type image forming apparatus is provided. The apparatus uses a developer that contains a mixture of a toner and a carrier, and includes a photosensitive body and a development unit. An electrostatic latent image is formed on the photosensitive body. The development unit includes a magnetic roller and a developing roller. The magnetic roller forms a magnetic brush containing the toner and the carrier on the outer periphery of the magnetic roller, and the developing roller is installed such that the developing roller does not contact the magnetic roller and the photosensitive body to develop the electrostatic latent image using the toner supplied from the magnetic brush. A resistivity of the developer is no greater than 109 Ωcm.

摘要： An electrophotography machine is disclosed that consistently produces images of optimum image density regardless of whether an ordinary sheet of paper or a transparency is used as the recording medium. A photosensor activated in response to the recording media passing a first sensor is positioned on the paper conveyance path and detects whether or not the recording media being processed is an ordinary sheet of paper or a transparency. A controller automatically applies the appropriate transfer voltage depending on whether or not the sheet of recording media is a sheet of paper or a transparency. The special design used in this invention does not require photosensors to be placed on the photosensitive drum or near any of the image forming apparatus. Thus, the device consistently produces optimum images while being easy and inexpensive to make and manufacture.
