Abstract: A toner amount detection sensor has a first light receiving element, a second light receiving element, and a toner amount calculation unit. The first light receiving element is provided on a side opposite to a light emitting element with respect to a plane extending in a direction perpendicular to a surface of a transfer belt. The second light receiving element is provided at a position avoiding a plane containing the light emitting element and the first light receiving element and is provided separately from the first light receiving element. The toner amount calculation unit calculates the toner amount from the light quantity of the light equivalent to the specular reflection light received by the first light receiving element and the light quantity of the diffuse-reflected light received by the second light receiving element.

Abstract: A toner-amount detection sensor includes a board, a sensor cover, a light emitter, a light receiver, a light-shielding wall, and two locking parts. The light emitter is surface-mounted on the board. The light receiver is surface-mounted on the board. The light-shielding wall is located between the light emitter and the light receiver, abuts the board, and abuts the sensor cover or extends from the sensor cover. The two locking parts are formed at opposite ends of the sensor cover to press the board to lock it from outside the light emitter and light receiver relative to the light-shielding wall, using the abutment between the light-shielding wall and the board as a supporting point.

Abstract: An image forming includes an apparatus main body, a photoreceptor drum, a charging apparatus, a developing device, a transfer apparatus, a charging bias applying unit, a developing bias applying unit, a bias adjusting unit, and a print density measurement unit. The bias adjusting unit forms a non-charged area on a circumference surface of the photoreceptor drum and applies a developing bias constituted of a first electric potential to a developing roller to form a first toner image by an electric potential difference between the non-charged area and the developing roller. The charging bias applying unit forms a second toner image by an electric potential difference between the electric potential area and the developing roller. The charging bias applying unit decides a value of a charging bias corresponding to a target electric potential from measurement results of print densities of the first toner image and the second toner image.

Abstract: A paper type detection apparatus includes a surface-property detection unit, a thickness detection unit, and a paper-type setting unit. The surface-property detection unit detects a surface property of paper by performing image processing on image data of the paper read by an image reading unit. The thickness detection unit causes the image reading unit to read the image data of the paper over which a reference chart with a predetermined black density is laid. The thickness detection unit detects the thickness of the paper based on the difference between the black density of the reference chart and the black density appearing on the image data through the paper. The paper-type setting unit sets the type of the paper associated with the detected surface property and thickness of the paper.

Abstract: An image forming apparatus includes an apparatus main body, a photoreceptor drum, a charging apparatus, an exposure apparatus, a developing device, a charging bias applying unit, a developing bias applying unit, an image condition adjusting unit, and a print density measurement unit. The image condition adjusting unit forms a second electric potential region by applying the charging bias where a first differential electric potential is subtracted from a first tentative charging bias on a circumference surface of a photoreceptor drum, and forms a second toner image by an electric potential difference between the second electric potential region and a developing roller by applying the target electric potential. The image condition adjusting unit decides value of the charging bias corresponding to the target electric potential from measurement results of print densities of a first toner image and the second toner image measured by the print density measurement unit.
