摘要： PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of correcting an inadequate scanning position on a photosensitive body by operating a lighting pattern of a semiconductor laser device. SOLUTION: When correcting is not carried out, a scanning speed on the photosensitive body differs according to portions so that an image in which the end section of the image is extended and the central section is compressed, is formed. Areas are defined on the photosensitive body according to the scanning speed. The scanning speed is primarily decreased as it approaches the center of the photosensitive body and is increased as it approaches the end section. Therefore, for example, an effective area of an image is divided into five blocks as is shown in Fig., the scanning is controlled by inserting no pixel piece in both of the end sections, inserting one pixel piece by each pixel in both of inner areas adjacent to the end sections and inserting two pixel pieces by each pixel in the central section. As a result, it is possible to obviate an f-θ lens. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To enable a cost reduction for products and to offset differences in an optical path length of two or more lasers in an image formation device with two or more lasers arranged in a vertical scanning direction to expose. SOLUTION: A modulation circuit 62 receives image data for every pixel and generates a pulse width signal relative to image data of each pixel. A modulation control section 70 determines an optical beam projection time duration per pixel in accordance with positions on a photo conductor surface where optical beams are to be projected. An output circuit 63 outputs a PWM signal formed by the modulation circuit 62 for every pixel over the optical beam projection time duration of matched pixels decided by the modulation control section 70. An optical beam relative to the PWM signal of each pixel outputted by the output circuit 63 is generated, and scanned and projected onto the photo conductor surface. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a paper conveyance device capable of specifying the presence or absence of abnormality and type of abnormality of the device, and to provide an image forming device. SOLUTION: This paper conveyance device is provided with: a pair of paper conveyance roller 406 and a back-up roller 407 for conveying paper on a conveyance path 408; a stepping motor 401 for driving the paper conveyance roller 406; a driver 402 for driving and controlling the stepping motor 401; and a current detection part 403 for detecting a value of current to be supplied into the driver 402. Since there is the relationship, [the normal time of the stepping motor 401]> [the time when roller pressure of the back-up roller 407 is insufficient] > [the time when the stepping motor 401 loses synchronism] with respect to an average value of the current values, the presence or absence of abnormality and type of abnormality (insufficient roller pressure of the back-up roller, loss of synchronism of the stepping motor) of the paper conveyance device are specified depending on the value of current to be supplied into the driver 402, for example, magnitude of the average value (integrated current value/detection period) of the current values in a detection period.

摘要： PROBLEM TO BE SOLVED: To reduce shift in image forming position which depends on the light quantity of a light beam. SOLUTION: In an image forming apparatus where the light quantity of a light beam being used for forming a latent image is switched depending on the difference of resolution, lasers 101 to 104 emit a light beam for forming a latent image on a photosensitive drum 203. A light beam thus emitted is used for scanning by a polygon mirror 105 and the scanned light beam is detected by a BD sensor 106. When controlling the emission timing of the lasers 101 to 104 depending on the timing the light beam is detected, a timing control section 204 selects a suitable emission timing from a table in a storage 205 depending on the light quantity of the light beam or the resolution.
