Filed: 1987-10-20
Abstract: PURPOSE:To prevent the dirt of a magnetic recording medium from generating by preventing the corona discharging processing to both sides of a non-magnetic supporting body when the corona discharging is executed to the non-magnetic supporting body. CONSTITUTION:In a process where a magnetic layer is applied to the surface to execute the corona discharging processing after the corona discharging processing is executed to a non-magnetic supporting body, for the corona discharging processing, the corona discharging is not executed to both edge sides of the cross direction (direction orthogonal to conveying direction and parallel to the surface to be the magnetic layer of the non-magnetic supporting body) of the non-magnetic supporting body. It is preferable that the width not to execute the corona discharging is the maximum value of the width not applied in the application of the magnetic layer. The width is usually about 5-10mm. In order to provide a part not to execute the corona discharging processing to both edge sides of the non-magnetic supporting body, a means to make an electrode width narrower than the width of the non-magnetic supporting body may be used.

Filed: 1989-10-11
Abstract: PURPOSE:To improve developing efficiency, to reduce developer remaining on a recording paper after development, and to prevent the soil and damage of the periphery, which results from developer scattering during development, by providing the liquid developing device with a developing roller which is housed in the hollow of the rod-like substrate of a developing head and which is rotated and driven with the periphery of the roller facing the opening of a developing slit. CONSTITUTION:Developer is sucked and introduced into the hollow part 23 of the rod-like substrate 21 of the developing head 20 by negative pressure, and the developing slit 22 is filled with the developer. A narrow gap is formed between the developing roller 26, part of which faces the developing slit 22, and the recording paper P, and the developer is sent into the gap as the developing roller 26 rotates. Since the negative pressure of the developing slit 22 of the developing head 20 is maintained during development, excess developer on the recording paper P is sucked and removed by the developing head 20 when the recording paper P passes on the developing head 20, and the developer does not flow out of the developing head 20. Thus, developing efficiency is improved, developer remaining on the recording paper after development is reduced, and soil and damage of the periphery, which results from developer scattering during development, can be prevented.
