摘要： An image forming apparatus calculates a positional deviation in the main and sub-scanning directions for each color by forming registration patterns in two arrays along a sub-scanning direction on an image carrier. Each registration pattern in one array is paired with an identical registration pattern in the other array. A first sensor has: a light-emitting element irradiating one registration pattern in a pair; a photodetector for regular reflection light; and a photodetector for diffuse reflection light. A second sensor has: a light-emitting element irradiating the other one in the pair; and a photodetector for regular reflection light. The relative positions of a pair of registration patters calculated using the respective sensors are corrected so as to reduce the positional deviation between the calculated positions by the amount of offset deviation estimated occur between positions detected by the respective sensors when the registration patterns are without positional deviation.

摘要： An image forming apparatus includes a toner carrier, a toner image forming unit, and a toner concentration sensor. The toner carrier includes a transparent film. The toner image forming unit forms a toner image onto the toner carrier. The toner concentration sensor senses the concentration of toner on the toner carrier. The toner concentration sensor includes first and second light emitting elements and a light receiving element. The light emitting elements each radiate light directly or indirectly to the toner carrier. The light receiving element receives reflecting light originating from the light emitting elements. The first light emitting element radiates light having a wavelength of a predetermined reflectance resulting from direct radiation to the toner carrier. The second light emitting element radiates light having a wavelength that causes a lower reflectance resulting from direct radiation to the toner carrier than a reflectance resulting from radiation to the toner.

摘要： An image forming apparatus has a moving part that operates for forming an image on recording paper. When an instruction to make a transition to a silent mode is input to an input unit, first control is executed so that operation noise of the moving part is reduced. When an instruction to cancel the silent mode is input to the input unit, second control is executed so that the operation noise of the moving part is increased stepwise to return to the state before the first control.

摘要： In an image formation state, to cool a recording sheet on a route from a fixer to a paper ejection roller, a blast fan assumes a first position restrained by a first fixture. Also, in another state, to cool a recording sheet on the catch tray, the blast fan assumes a second position restrained by a second fixture. To transition from the image formation state to another state, the blast fan sends a strong blast in a reverse direction from the normal blast direction. A bias is generated on the blast fan due to the resulting reactive force, the blast fan becomes free from the restraint of the first fixture, and shifts from the first position to the second position. Conversely, to transition from another state to the image formation state, a strong blast is sent in the same direction as the normal blast direction, and the blast fan shifts from the second position to the first position.

摘要： An image forming device that uses only one temperature sensor to detect temperatures of the recording sheet and a rotation member for fixing, and can perform the temperature adjustment control carefully in detail during the image forming operation. The CPU 61 performs the temperature adjustment control 1 by executing the temperature adjustment program 64b (step S109), then executes the paper passing judgment program 64a to judge whether or not paper is passing (step S110). As far as it judges that no paper is passing (NO in step S110), the CPU 61 continues to perform the temperature adjustment control 1 by executing the temperature adjustment program 64b. When it judges that paper is passing (YES in step S110), the CPU 61 performs the temperature adjustment control (step S112).

摘要： In this toner concentration sensor, as the magnetic permeability of a two-component developer 3 containing toner and carrier in a two-component developing unit 1 has changed with changing TC ratio of the two-component developer, the oscillation frequency of a first oscillation circuit 20 having a detection coil 5 changes, on the other hand the oscillation frequency of a second oscillation circuit 30 having a reference coil 6 does not change. While, changes in temperature conditions cause the oscillation frequency of the second oscillation circuit to change in the same way as the oscillation frequency of the first oscillation circuit. Therefore, utilizing a difference between the oscillation frequencies of the first and second oscillation circuits makes it possible to cancel out changes in the temperature conditions so that a value corresponding to only the magnetic permeability of the two-component developer can be obtained. Thus, detection errors of toner concentration due to temperature changes can be reliably prevented.
