摘要:
This invention relates to an image forming apparatus which has a recording material support member for supporting a recording material and moving therewith, an image forming unit for forming an image on the recording material supported by the recording material support member, and attraction charging devices for electrostatically attracting the recording material to said recording material support member. The attraction charging devices are first and second electrodes positioned across the recording material support member from each other, wherein a center of charging of the first electrode to the recording material support member is shifted from a center of charging of the second electrode, in the moving direction of said recording material support member, and there may also be an auxiliary charger for charging, prior to image formation, the recording material attracted to the recording material support member.

An image forming apparatus comprising an image bearing member, a transfer material support member, fixing means and oil removing means for removing the oil deposited to the transfer material support member.The image forming apparatus selects either a first mode in which, after the fixation of the image by the fixing means on a first face of the transfer material, the transfer material bearing the fixed image on the first face is automatically supported on the transfer material support member to transfer an image of the image bearing member to a second face different from the first face of the transfer material, or a second mode in which, after the fixation of the image by the fixing means on a first face of a manually inserted transfer material, the transfer material is discharged from the apparatus without image formation on a second face different from the first face of the transfer material. In case of selection of the first mode, the oil removing means do not effect the oil removal after the transfer of the image of the image bearing member to the first face of the transfer material but effects the oil removal after the transfer of the image of the image bearing member to the second face of the transfer material, while, in case of selection of the second mode, the oil removing means effects the oil removal after the transfer of the image of the image bearing member to the transfer material regardless whether the manually inserted transfer material has passed the fixing means.

A decorative sheet has a structure of: a laminate sheet having a base film and a decorative layer formed on the base film; and a surface resin layer having a transparent resin layer and a printed layer formed in an image pattern on the transparent resin layer, being laminated on the laminate sheet at the decorative layer side. The surface resin layer is laminated so as the printed layer to come to the laminate sheet side, the surface of the laminate sheet at the decorative layer side forms an indented profile having concavities on the decorative layer recessed to the base film side, and the printed layer enters the concavities. The printed layer is a layer formed by printing a printing liquid containing a photocuring component containing polyurethane and polyester, a thermoplastic resin, and a solvent, in an image pattern on the transparent resin layer, and by removing the solvent from the printed printing liquid, and then by curing the photocuring component under light irradiation.
摘要:
In a buried type structure including an active layer sandwiched between an n-type cladding layer and a p-type cladding layer and a current blocking layer having an opening for confining a current flowing to the active layer, a regrown layer made of a nitride semiconductor doped with a p-type impurity is formed on the current blocking layer so as to cover the opening of the current blocking layer, and a portion of the regrown layer buried in the opening disposed to be adjacent to a side face of the opening and having a given width W is changed to have the n-type conductivity. Accordingly, the opening of the current blocking layer is effectively narrowed, so as to realize a self-pulsation nitride semiconductor laser device.
