摘要： A fixing unit includes an endless belt accommodating a heat source inside a loop formed by the endless belt, a rotary pressing member rotating in contact with the endless belt in a pressure contact section, and a heat transfer member secured to a side plate within the loop of the endless belt to support and heat the endless belt with heat conducted from the heat source. The heat transfer member has an opening opposite the rotary pressing member. A securing member is disposed in the opening of the heat transfer member in pressure contact with the rotary pressing member via the endless belt. The heat transfer member and the securing member collectively include a pair of latching parts to firmly connect the heat transfer member and the securing member with each other when one of the latching parts is fitted to the other one of the latching parts.

摘要： A fixing device includes a fixing rotary body and a pressing rotary body disposed opposite the fixing rotary body. A pivotable pressurization member contacts and presses the pressing rotary body against the fixing rotary body. A pressurization pivot is provided on the pressurization member. A depressurization member, pivotable about the pressurization pivot, causes the pressurization member to isolate the pressing rotary body from the fixing rotary body. A depressurization pivot is provided on the depressurization member. A lock is pivotable about the depressurization pivot and engageable with the pressurization pivot. A biasing member, anchored to the lock, exerts a resilient bias that allows the lock to cause the pressurization member to press the pressing rotary body against the fixing rotary body. A detent is situated in a pivotal trajectory of the lock to restrict pivot of the lock by contacting the lock.

摘要： A fixing device includes an endless belt and an opposed rotary body contacting an outer circumferential surface of the belt. A nip formation pad contacting a first part of an inner circumferential surface of the belt presses against the opposed rotary body via the belt to form a fixing nip between the belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A heat conductor disposed opposite a second part of the inner circumferential surface of the belt not contacted by the nip formation pad is interposed between a heater and the belt to conduct heat from the heater to the belt. A reflector disposed inside the loop formed by the belt reflects light from the heater toward the heat conductor. The reflector and the heat conductor surround the heater.

摘要： A process cartridge for an image forming apparatus includes an image bearer; a developer bearer to supply a latent image on the image bearer with toner and develop the latent image, a cleaner to clean residual toner on the image bearer after a transfer process, and an elastically deformable remover to contact an end portion of the image bearer in an axial direction of the image bearer. The remover includes an inclined part extending in the axial direction of the image bearer from an upstream side to a downstream side in a direction of movement of the image bearer. The inclined part includes a contact portion to contact the image bearer. The contact portion of the inclined part forms a gradient in the axial direction.
