摘要： An image forming apparatus includes a plurality of latent image bearers, a latent image writer, a plurality of developing units, a primary transfer unit, a secondary transfer unit, an adjuster, a pattern image formation controller, a color deviation detector, a color deviation correction controller, and an image-formation-mode setting unit. The latent image writer writes latent images to the latent image bearers. The plurality of developing units develops the latent images of the latent image bearers and form toner images of different colors. The primary transfer unit transfers the toner images on the latent image bearers to an intermediate transferer. The secondary transfer unit transfers the toner images from the intermediate transferer to a sheet. The adjuster causes the intermediate transferer and the secondary transfer unit to be in a contact state or a separated state. The pattern image formation controller forms a pattern image on the intermediate transferer via the latent image bearers to detect color deviation. The color deviation detector detects the color deviation of the pattern image borne on the intermediate transferer. The color deviation correction controller executes color deviation correction control in the separated state. The image-formation-mode setting unit sets a normal linear-velocity image formation mode in which an image is formed at a normal linear velocity and at least one non-normal linear-velocity image formation mode including a low linear-velocity image formation mode in which an image is formed at a low linear velocity slower than the normal linear velocity. A plurality of image formation velocities including the normal linear velocity and the low linear velocity is set, and an execution timing of the color deviation correction control in image formation at the normal linear velocity and an execution timing of the color deviation correction control in image formation at the low linear velocity are set independently from each other.

The pressing member contacts an outer circumferential surface of the fixing member to form a fixing nip between the fixing member and the pressing member through which a recording medium bearing a toner image passes. The heater heats the fixing member to a predetermined temperature based on a detection result provided by the temperature detector. A circumferential distance A between the temperature detector and the heater along a circumference of the fixing member is defined by the following formula: A≧v×(T1+T2) where v is a circumferential velocity of the fixing member rotating in a predetermined direction of rotation, T1 is a response time of the temperature detector, and T2 is a response time of the heater.

摘要： In a fixing device, a first reflection plate covers a part of an outer circumferential surface of an infrared heater in a circumferential direction of the infrared heater along an axial direction of the infrared heater substantially perpendicular to the circumferential direction of the infrared heater. The first reflection plate reflects light emitted by the infrared heater toward a fixing member. At least one light control mirror is provided in at least one end of the first reflection plate in an axial direction of the first reflection plate. At least one second reflection plate opposes the infrared heater via the at least one light control mirror to reflect the light emitted by the infrared heater and passing through the at least one light control mirror toward a center portion of the fixing member in an axial direction of the fixing member.
