    摘要： The present invention provides a projection display device configured to solve a caption dropout problem. CPU 3 determines a correction amount required to correct an image signal for distortion. Scaler 4 corrects the image signal for distortion based on the correction amount. Caption signal processing circuit 5 adjusts the display content of a caption signal based on the correction amount in such a manner that the entire caption indicated by the caption signal is displayed. Display image generation circuit 6 synthesizes the caption signal with the display content thereof adjusted by caption signal processing circuit 5, with the image signal corrected by scaler 4. Projection section 7 projects the synthesized image signal.

    摘要： An image forming apparatus includes an image carrying member, an intermediate transfer member, a charging member, a transfer mechanism, a discharging member, a direct current voltage source, and a direct current voltage controller. The intermediate transfer member is deposited at a position facing and in contact with the image carrying member rotatably carrying a toner image on a rotating surface, and receives the toner image therefrom during a first transfer operation. The charging member applies a charge to the intermediate transfer member to cause an electric field around a region where the image carrying member and the intermediate transfer member contact with each other, where the electric field generates a force for initiating the first transfer operation. The transfer mechanism performs a second transfer operation for transferring the toner image from the intermediate transfer member to a transfer sheet. The discharging member performs a discharging operation for discharging the charge remaining on the intermediate transfer member with contacting the intermediate transfer member after a completion of the second transfer operation. The direct current voltage source applies a direct current voltage to the discharging member to cause the discharging member to perform the discharging operation. The direct current voltage controller controls the direct current voltage in accordance with a volume resistivity of the intermediate transfer member.
