摘要： The pressure between a developing roller and a photosensitive drum is set to 0.24 MPa. Because the pressure is smaller than 0.31 MPa, if the potential difference ΔV between the non-image forming part on the photosensitive drum and the electrically-charged polymer toner on the surface of the developing roller is at the preset proper voltage (300 volts), pressure fogging will be prevented. Because the pressure is 0.24 MPa or less, even if the potential difference varies within the range of 200 volts to 400 volts that occurs in practice, pressure fogging will be prevented. By resetting the pressure to 0.22 MPa, even if the potential difference ΔV varies in a wider voltage range of 100 to 400 volts, pressure fogging will be prevented. In this way, by setting the pressure between the developing roller and the photosensitive drum appropriately, pressure fogging can be prevented even when using the opposite-direction developing method and polymer toner.
摘要翻译：显影辊和感光鼓之间的压力设定为0.24MPa。由于压力小于0.31MPa，如果感光鼓上的非图像形成部分和显影辊表面上带电的聚合物调色剂之间的电位差DeltaV处于预设的适当电压（300伏），防止压力起雾。由于压力为0.24MPa以下，所以即使电位差在实际发生的200〜400V的范围内变化，也可防止压力起雾。通过将压力重置为0.22MPa，即使电位差DeltaV在较宽的100〜400V的电压范围内变化，也可防止压力起雾。以这种方式，通过适当地设置显影辊和感光鼓之间的压力，即使使用相反方向的显影方法和聚合物调色剂也可以防止压力起雾。

摘要： An image forming apparatus for forming an image on a photosensitive recording medium by exposing the photosensitive recording medium to light by way of a mask member which is placed on an exposure station. The apparatus comprises a first transport device which transports the mask member through the exposure station and a second transport device which transports the photosensitive recording medium through the exposure station. A first exposure unit irradiates light upon the photosensitive record medium by way of said mask member at the exposure station to record an image formed on the mask member on the photosensitive recording medium. Alternatively, when a mask member is not used, a second exposure unit directs light through an auxiliary member having a light-passing image thereon to project and record the light-passing image onto the photosensitive recording medium.

摘要： An image recording apparatus has an exposing device in which the light from a light source is irradiated to an original text and a photosensitive, pressure-sensitive paper is exposed to the light from the text in correspondence to the image of the text. The image recording apparatus is designed so that the light source and the photosensitive, pressure-sensitive paper have a relative movement by means of a movement device, with the moving speed being varied by means of a moving speed control device. The duration of exposure of the photosensitive, pressure-sensitive paper by the exposing device is varied in response to the moving speed, whereby the level of exposure can be varied. Accordingly, this image recording apparatus, which is simple in structure, accomplishes a variable exposure level for the photosensitive, pressure-sensitive paper without the need of varying the light output of the light source and regardless of the type of the light source.
