  • Patent number: 11474458
    Abstract: A control circuit executes voltage adjustment processing of adjusting a voltage output from a transfer power source so that a current detected by a detection circuit becomes a predetermined current value. The voltage adjustment processing is executed before a toner image is transferred from at least one of a first image bearing member and a second image bearing member to an intermediate transfer belt. A processor determines whether the second transfer member is in a state of contact or is in a state of separation on the basis of behavior of the current detected by the detection circuit in a period in which the control circuit is executing the voltage adjustment processing.

  • Patent number: 11409229
    Abstract: A control device permits execution of a print process on condition that an object sensor detects an object at a detection position. A switch mechanism, in accordance with a release operation, releases an interlock between a first displacement member and a closing operation of a cover portion. In a state where a second displacement member is located at an actuation position, a detected portion is located at the detection position. When the second displacement member is located at a retreat position, a first contact portion is not in contact with the cover portion. When the cover portion is closed, the cover portion displaces the second displacement member from a standard position to an actuation position. When the first displacement member is displaced from a first relay position to a second relay position, the first displacement member displaces the second displacement member from the standard position to the retreat position.

  • Patent number: 9412056
    Abstract: An image forming apparatus includes individually replaceable image forming assemblies forming images of different colors; a storage portion that stores time when at least one image forming assembly currently loaded into the apparatus is unloaded; a calculating portion that calculates an unloaded-engine storage period, time elapsed from when a newly loaded image forming assembly is unloaded last time to when the image forming assembly is newly loaded; and a controller that performs image quality adjustment depending on the unloaded-engine storage period calculated before the newly loaded image forming assembly is used for image formation. The apparatus receives image data of an image that contains a color other than colors that currently loaded image forming assemblies form. The apparatus forms a final image based on the image data on a sheet through image forming operations on the same sheet while at least one of the loaded image forming assemblies is replaced.

  • Patent number: 9348310
    Abstract: In an image forming apparatus, a first cooling unit sends airflow to cool a first developing unit, and a second cooling unit sends airflow to cool a second developing unit. A control section controls the first and second cooling units in a first mode where image formation is executed using both a first and second image forming section, and in a second mode where image formation is executed such that the first developing unit is suspended but the first image bearing body is driven, using an image forming section. In the first mode the first cooling unit is controlled based on an output of a first temperature sensor regardless of a temperature detected by a second temperature sensor, and in the second mode the first cooling unit is controlled based on an output of the second temperature sensor regardless of a temperature detected by the first temperature sensor.

  • Patent number: 9164436
    Abstract: A fixing device includes a fixing section that includes rotatable members arranged to form a nip area through which a strip-shaped medium passes, and heaters that heat the rotatable members; and a control section. The fixing section applies heat and pressure to a toner image that is formed on the medium and passes through the nip area via the rotatable members heated by the heaters to fix the toner image onto the medium. The control section performs such control that the rotation of the rotatable members is stopped when the temperature of contact portions of the rotatable members that are in contact with the medium is lower than or equal to a first temperature that is lower than a temperature at which a portion of the medium softens.
