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 using a set of mask members and having mask position adjusting device. A transparent mask member supporting plate is provided at the exposure position. Each of the mask member is delivered upon the mask member supporting plate by two pairs of rollers. In this mask delivery, a mask image surface faces upwardly. An elongated photosensitive recording medium is positioned immediately above the mask member supporting plate so as to guide the medium at the exposure position. Further, an exposure device including a light source and color filters is positioned below the mask member supporting plate. The mask member undergoes positional adjustment at the exposure position. For this, the mask member supporting plate is supported on a positioning frame which is movable in a direction perpendicular to the mask member moving direction. The position of the mask member with respect to the running direction thereof is controllable by controlling rotations of two pairs of rollers, and the mask position with respect to its tranverse direction is controllable by controlling the movement of the positioning frame.

摘要： In forming a color picture image on a photosensitive recording medium by exposing through a masking master plate, the plate is conveyed by a conveyor belt into an exposure device where the plate must be registered in a specified position to avoid a color shift in the image formed on the photosensitive recording medium. A positional error or deviation of the plate is detected by reading out a location mark on the plate by a plurality of sensors. According to the outputs from the sensors, the conveyor belt is moved in a longitudinal path by one or two motors to correct a longitudinal deviation, and two longitudinally spaced portions of a belt support unit are moved, in a direction perpendicular to the longitudinal path, independently and respectively by other two motors to correct a transverse deviation and/or a skew.

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。
