摘要： A biasing force adjusting device includes a roller, a roller holder, a first biasing member, and a second biasing member. The roller faces a mover. The roller holder holds the roller and is displaceable with respect to the mover. The first biasing member applies a first biasing force to the roller holder to press the roller against the mover. The second biasing member applies a second biasing force greater than the first biasing force to the roller holder to press the roller against the mover.

摘要： A powder conveying device includes a drop conveyance passage, an intersecting conveyance passage, a conveying screw, and a floating member. Powder entering from an inflow port drops in the drop conveyance passage. The intersecting conveyance passage communicates with a lower end of the drop conveyance passage and extends in an intersecting direction that intersects the drop conveyance passage. The conveying screw is disposed in the intersecting conveyance passage and rotates in a specified direction to convey the powder in the intersecting direction. The floating member is movably installed in the drop conveyance passage and floats in the drop conveyance passage to move by contact with the conveying screw. The inflow port and the floating member interfere with each other to prevent the floating member from coming out of the inflow port of the drop conveyance passage.

摘要： An image forming apparatus includes a toner image bearer, a transfer device, a cleaner, a bias power source, and circuitry. The toner image bearer bears a toner image. The transfer device performs a transfer process The cleaner contacts the toner image bearer to remove transfer residual toner that is subject to the transfer process and remove untransferred toner that is not subject to the transfer process. The bias power source applies one of a first bias and a second bias different from the first bias to the cleaner. The circuitry controls the bias power source to output the first bias to the cleaner in response to a start of an image forming operation to remove the untransferred toner from the toner image bearer and control the bias power source to switch an output from the first bias to the second bias.

摘要： A roller unit includes a roller, an arm, a holder, a tension spring, and a restriction member. The arm rotatably holds the roller. The holder swingably holds the arm. The tension spring includes a first hook at one end of the tension spring and a second hook at another end of the tension spring. The first hook is hooked on an arm-side hook of the arm. The second hook is hooked on a holder-side hook of the holder. The restriction member is configured to restrict movement of the tension spring in a state in which the first hook or the second hook is unhooked.

摘要： An image forming apparatus includes a rotatable image bearer, a transfer rotator, a detector, and circuitry. The image bearer bears an image. The transfer rotator transfers the image from the image bearer onto a recording medium sandwiched and conveyed between the image bearer and the transfer rotator. The detector detects length information indicating a length, in a direction of conveyance of the recording medium, of the image on the recording medium. The circuitry corrects a correction value, based on the length information detected by the detector and a target value of the length information, to correct an image magnification, in the direction of conveyance of the recording medium, of the image to be formed on the recording medium. The circuitry controls an image forming operation of forming the image on the recording medium with the correction value.

摘要： A process unit includes a rotatable image bearer, an optical writing head to expose the image bearer within an maximum exposure range in an axial direction of the image bearer, a developer bearer, spacers disposed in axial end portions of the image bearer to determine a position of the optical writing head relative to the image bearer and slidingly contact the image bearer, a cleaner disposed downstream from the developer bearer in an image bearer rotation direction, and a remover to slidingly contact the axial end portion of the image bearer to remove a substance adhering thereto. In the axial direction, inner ends of the spacers are positioned inside a toner layer range of the developer bearer extending beyond a largest sheet width. The remover is disposed downstream from the cleaner and crossing a line extending from the inner end of the spacer perpendicularly to the axial direction.
