20120237231 | INFORMATION PROCESSOR, IMAGE FORMING APPARATUS, INFORMATION PROCESSING METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM - An information processor includes a storage unit storing a first coefficient in correspondence with a characteristic of a sheet of paper, a first acquisition unit acquiring a first signal based on the water content of a first sheet of paper not having an image formed thereon, a second acquisition unit acquiring a second signal based on the water content of the first sheet of paper having an image formed thereon and being heated for fixing, a determination unit determining the characteristic of the first sheet of paper, a first calculation unit calculating a variation in water content of the first sheet of paper using the difference between the first signal and the second signal and the first coefficient stored in correspondence with the determined characteristic, and a second calculation unit calculating an expansion and contraction ratio of the first sheet of paper using the variation in water content. | 2012-09-20 |
20120237232 | PRINTING APPARATUS - A printing apparatus includes an image forming section which forms a toner image of the image to be printed on a recording medium; a transport belt which transports the toner image formed by the image forming section; a light-emitting section which emits a light to the transport belt; a first light-receiving section which is disposed at a position through which a regular reflection light, of the light emitted from the light-emitting section, reflected from the transport belt passes; a second light-receiving section which is disposed at a position different from the position of the first light-receiving section; a transmissive member which is disposed at a position through which the light emitted from the light-emitting section and a reflection light, of the light, reflected from the transport belt pass and which transmits the light and the reflection light. | 2012-09-20 |
20120237233 | IMAGE FORMING APPARATUS AND IMAGE DENSITY CONTROL METHOD - An image forming apparatus including an image carrier; an intermediate transfer member having a first portion and a second portion that has a higher glossiness than that of the first portion; a primary transfer member; a light source to emit light to the intermediate transfer member side; a detector to detect intensity of reflected light emitted from the light source and then reflected from the intermediate transfer member and a density adjustment pattern formed on the intermediate transfer member; a processor including a light-emission intensity adjuster to adjust light-emission intensity from the light source based on detected intensity of light reflected from the second portion of the intermediate transfer member; and an image forming condition controller to control image forming conditions for forming a toner image based on the detected intensity of the light reflected from the density adjustment pattern formed on the intermediate transfer member. | 2012-09-20 |
