摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of decreasing generation of image forming under an improper printing condition. SOLUTION: An area sensor for imaging a reflecting image of a recording material surface irradiated with light from an obliquely upward direction and a transmitting image of the recording material surface irradiated with light from the back of the back surface, is incorporated, and a kind of the recording material (information necessary for recording on the recording material) is determined in accordance with the result of analysis on the reflecting image and the transmitting image captured by the area sensor to set an image forming condition.

摘要： PROBLEM TO BE SOLVED: To ensure fixing, etc. on any of various kinds of recording materials under optimum fixing conditions while improving usability, by discriminating the types of the recording materials. SOLUTION: In the case where paper types are similar, a fixed first or second value as a threshold may make it difficult to discriminate the paper types. Here, a threshold y is obtained by assigning the second value to x of threshold calculation formula (1): y=-04x+35. When the first value is greater than the calculation result y, a paper type a is discriminated. When it is not greater than the threshold y, a paper type b is discriminated. This makes it possible to obtain reliable result of identification compared to the result depending on the fixed thresholds. Specifically, where the first value>y, the paper type a is discriminated, and where the first value ≤y, the paper type b is discriminated. COPYRIGHT: (C)2006,JPO&NCIPI

解决方案：在纸张类型相似的情况下，作为阈值的固定的第一或第二值可能使得难以区分纸张类型。这里，通过将第二值分配给阈值计算公式（1）的x来获得阈值y：y = -04x + 35。当第一个值大于计算结果y时，区分纸张类型a。当不大于阈值y时，区分纸张类型b。这使得与根据固定阈值的结果相比，可以获得可靠的识别结果。具体地说，在第一个值> y的情况下，区分纸张类型a，并且在第一个值≤y的情况下，区分纸张类型b。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To achieve fixing, etc., under the optimum fixing conditions even on various types of recording materials while improving usability by highly accurately discriminating the type of the recording material. SOLUTION: An image reading sensor 123 includes a reflecting LED 301, an LED 303 which is disposed opposite from recording material 304 and detects transmitted light quantity, a CMOS area sensor 211, and an image forming lens 303. Light from the reflecting LED 301 as a light source is emitted to the surface of the recording material 304. The light reflected from the recording material 304 is condensed via the lens 303 and forms an image in the CMOS area sensor 211. In such a case, a diffusing plate or a diffusible light guide is used between a transmitting LED 302 and the recording material 304. This removes irregularities in the light source and improves measuring accuracy. COPYRIGHT: (C)2005,JPO&NCIPI
