摘要:
An image forming apparatus having a photoconductor for carrying a toner image; a transfer device, provided with a discharge wire, for transferring the toner image onto a transfer material through discharge in a transfer area, after a transfer material is superposed with the photoconductor; a transfer-exposure device for carrying out light exposure of a surface of the photoconductor superposed with the transfer material, in the transfer area; a separator for separating the transfer material from the photoconductor after the toner image is transferred; and a controller for controlling the image forming apparatus. The controller controls such that light from the transfer-exposure device is applied to the photoconductor surface for the first time when the photoconductor surface superposed with the transfer material has reached the transfer area.

An image forming apparatus includes: a drum-shaped image carrier; a transfer and separation device which includes a conveyor belt for conveying a transfer material, a transfer roller for supporting the conveyor belt, and a nip regulating roller that is disposed downstream of the transfer roller in a conveyance direction of the transfer material; a transfer region changing section adapted to change a downstream end of the transfer region in a conveyance direction of the transfer material by changing a position of the nip regulating roller; and a transfer pressure changing section which changes a transfer pressure that corresponds to a pressure by the transfer roller against the image carrier, wherein the transfer pressure changing section changes the transfer pressure in correspondence with the change of the downstream end of the transfer region by the transfer region changing section.
摘要:
A first bar code that is reproduced by linearly polarized red light (first read light) parallel to a short-side direction and a second bar code that is reproduced by linearly polarized green light (second read light) parallel to a long-side direction are recorded on a birefringence label. A probe is a reading device that reads the first and second bar codes from the birefringence label and includes first and second light sources and an imaging unit. The first light source emits the first read light to the birefringence label. The second light source emits the second read light to the birefringence label at a time different from that of the first read light. The imaging unit captures the birefringence label through a polarizing plate having a transmission axis aligned with the short-side direction of the birefringence label, and acquires reproduced images of the first and second bar codes.
摘要:
A product comprising a patterned optically anisotropic layer having two or more regions of different birefringence in the form of a pattern, comprising at least an intensity gradation-type pixel of approximately uniform birefringence and an area gradation-type pixel comprising two or more of drawing units of different birefringence, and each region of a single birefringence in the patterned optically anisotropic layer comprising a plurality of the drawing units is provided. The product permits the formation of full-color images (latent images) and includes delicate color representation, such as the densities of particular colors.
