A method of printing a toner, including: rotating a cylinder having a printing plate with a fixed pattern; transferring a toner from a vessel onto the fixed pattern of the printing plate, in which the toner includes a pigment with a metallic reflective layer; and transferring the toner onto a substrate; in which the fixed pattern defines select portions of an image; and in which the toner correlates to the selected portions of the image is disclosed.

A development system for an image forming apparatus includes a photosensitive drum having a drive plate to receive a driving force to rotate the photosensitive drum. The drive plate is provided on an end of the photosensitive drum. The development system also includes a developing roller having a clutch mechanism to dampen a force generated when the clutch mechanism engages the drive plate of the photosensitive drum. The clutch mechanism is provided on an end of the photosensitive drum.

In one example, an apparatus includes a plate configured to pivot about a pivot point, a pulley coupled to a first planar side of the plate and configured to rotate a belt, a motor coupled to the first planar side of the plate and configured to drive the pulley, and a torsion spring coupled to a second planar side of the plate that is opposite the first planar side and configured to apply tension to the belt.

A transfer device includes a movable component, a moving assembly, a restrictor, and an operating member. The movable component moves toward and away from a latent image bearer unit. The moving assembly causes the movable component to move toward and away from the latent image bearer unit. The restrictor restricts the latent image bearer unit from detaching from an image forming apparatus. The operating member causes the moving assembly to move the movable component away from the latent image bearer unit and releases restriction of detachment of the latent image bearer unit from the image forming apparatus by the restrictor.

An image forming apparatus includes a housing unit that includes an intermediate plate, a lift-up unit, a first detection unit, a second detection unit, a feeding unit, a control unit, a first acquisition unit that acquires a first driving amount, a storage unit that stores a threshold, a determination unit that determines that a recording material is overloaded on the intermediate plate when the first driving amount is smaller than the threshold, a second acquisition unit that acquires a second driving amount, a correction unit that obtains a differential amount by subtracting a predetermined driving amount from the second driving amount acquired by the second acquisition unit, and corrects, on a basis of the differential amount, the threshold stored in the storage unit or the first driving amount acquired by the first acquisition unit.

A driving device includes a motor including a shaft portion provided with a gear portion; a side plate provided with a first hole through which the motor engages with the side plate and a second hole connecting with the first hole; a gear configured to engage with the gear portion provided on the shaft portion when the motor is fixed in the first hole, so as to be rotatable through transmission of a driving force from the motor; and a flexible cover member configured to cover the second hole, wherein the cover member contacts the shaft portion of the motor when the shaft portion of the motor is inserted into the second hole.

In one example, an apparatus includes a plate configured to pivot about a pivot point, a pulley coupled to a first planar side of the plate and configured to rotate a belt, a motor coupled to the first planar side of the plate and configured to drive the pulley, and a torsion spring coupled to a second planar side of the plate that is opposite the first planar side and configured to apply tension to the belt.

A heating system includes a heater compatible with plural heating methods and configured to heat a heating target in a non-contact manner, and one or more processors. The one or more processors are configured to switch a heating method to be used for heating the heating target depending on a material of the heating target.

A developing device includes a housing, a developing roller, a developer conveyance path, a partition plate, a developer supply port and a developer conveying member. The developer conveying member rotates such that an outer peripheral part thereof moves from top to bottom in a first area between a second shaft portion and the partition plate and moves from bottom to top in a second area between the second shaft portion and the side wall. The developer supply port is obliquely open above the second area. The housing includes a first space formed above the second area of the first conveyance path and a second space formed up to a position higher than the partition plate to communicate with the first conveyance path above the first area of the first conveyance path and communicating with the first space in a horizontal direction.
