Abstract: In a light guide member included in an image forming apparatus, a transmitting/reflecting portion transmits and reflects light that is emitted from a light source to enter one end of the light guide member in a longitudinal direction and be guided to the other end thereof in the longitudinal direction. The light reflected by the transmitting/reflecting portion is emitted from a first optical surface. The light transmitted through the transmitting/reflecting portion is emitted from a second optical surface. At a cross section orthogonal to the longitudinal direction, a first outer peripheral surface has an arc shape including the first optical surface. Second outer peripheral surfaces expand from both ends of the first outer peripheral surface toward the second optical surface.

Abstract: An image forming apparatus includes an image carrier, a developing device, a control unit, and a density measuring unit. An electrostatic latent image is formed on the surface of an image carrier. A developing device supplies toner to the image carrier and develops the electrostatic latent image formed on the image carrier to form a toner image. The density measuring unit measures the toner density of the plurality of first patch toner images formed by the developing device. The control unit calculates a relationship between the toner density of the plurality of first patch toner images measured by the density measuring unit and the applied voltage applied to the developing device when the plurality of first patch toner images are formed, and adjusts the applied voltage based on a calculation result.

Abstract: An image forming apparatus performs a halftone process using plural dither matrices. Generated is calibration data to calculate a color registration error amount corresponding to a primary scanning directional position of an image forming available width. An image area dividing unit determines an image boundary position that is identical to any of matrix boundaries of plural dither matrices arranged in an image forming target area, and divides the image forming target area into plural image adjustment areas using the image boundary position. A correction processing unit corrects secondary scanning directional positions of the plural image adjustment areas, using respective correction amounts calculated with the calibration data. Further, the image area dividing unit determines the image boundary position using a remainder left by dividing in the primary scanning direction the number of pixels of the image adjustment area by the number of pixels of the dither matrix.

Abstract: An image forming apparatus includes a charging roller, a temperature sensor, a humidity sensor, a sampling part, a life consumption degree calculating part and a warning processing part. The sampling part executes temperature/humidity inputting process inputting temperature of the temperature sensor and humidity of the humidity sensor. The life consumption degree calculating part calculates a life consumption degree of the charging roller from a last time to a present time in the temperature/humidity inputting process by applying respective representative values of last and present inputted temperature and humidity into a model formula. The warning processing part outputs a warning when an addition value of the life consumption degrees exceeds a predetermined threshold value. The life consumption degree calculating part uses the model formula deriving larger life consumption degree in a case where the representative value of the temperature and the representative value of the humidity are respectively larger.

Abstract: An image forming apparatus includes a heating element, an interior temperature/humidity detection section, and a controller. The heating element is conducted during connection of the image forming apparatus to an external power source to heat an image bearing member. The interior temperature/humidity detection section detects temperature and humidity in the interior of the image forming apparatus. The controller performs a refresh operation when a relative humidity calculated on the basis of the temperature and humidity detected by the interior temperature/humidity detection section immediately after the image forming apparatus is connected to the external power source is higher than the preset value. The refresh operation is an operation for supply of developer from a development device to the image bearing member and for polish of the surface of the image bearing member with the use of a polishing member.
