摘要： A fixing device (20) includes a belt (29), a nip formation pad (26), and a pressure rotator (30). The belt (29) has a loop rotatable in a sheet conveyance direction. The nip formation pad (26) is inside the loop and includes three curved portions (26a, 26b, 26c) in the sheet conveyance direction. The three curved portions (26a, 26b, 26c) form a nip formation face. The pressure rotator (30) presses the belt against the nip formation pad (26) to form a fixing nip between the belt and the pressure rotator (30).

摘要： The present invention relates to a developer supply container detachably mountable to a developer receiving apparatus, the developer receiving apparatus including a developer receiving portion provided with a receiving port for receiving a developer and including a portion-to-be-engaged capable of displacing integrally with the developer receiving portion, the developer supply container comprising: a rotatable developer accommodating portion for accommodating the developer; a discharging portion provided at a bottom side thereof with a discharge opening for discharging the developer accommodating in the developer accommodating portion; and an engaging portion engageable with the portion-to-be-engaged with a mounting operation of the developer supply container to displace the developer receiving portion in a displacing direction so as to bring the receiving opening into fluid communication with the discharge opening. The engaging portion has such a shape that a first angle relative to a mounting direction of the developer supply container at a downstream end portion in the mounting direction is larger than a second angle relative to the mounting direction at an upstream end portion in the mounting direction.

摘要： Provided are an imaging device and an imaging method thereof, and a printer. The imaging device includes: M rotatable photosensitive drums (2), at least one display chip (1), at least one projection lens, and at least one beam deflection system (3). Each photosensitive drum (2) is configured to form an electronic latent image in a light-receiving region of each photosensitive drum (2) through exposing the light-receiving region. M is greater than or equal to 1. The light-receiving region of each photosensitive drum (2) includes multiple light-receiving sub-regions arranged in the axial direction of the photosensitive drum (2). Each display chip (1) includes at least two light-emitting regions arranged in a first direction. Light-emitting regions of the at least one display chip have a one-to-one correspondence with light-receiving sub-regions of the M rotatable photosensitive drums. At least one projection lens is in one-to-one correspondence with the at least one display chip (1). Each projection lens is configured to form an image for a corresponding display chip (1). The at least one beam deflection system (3) is in one-to-one correspondence with the at least one display chip (1). The beam deflection system (3) is configured to deflect an image, which is formed by each light-emitting region in the display chip (1) through a corresponding projection lens, to a corresponding light-receiving sub-region.
