摘要： A removable unit that is attachable to and detachable from a body of an apparatus includes a positioning projection and an upstream projection. The positioning projection projects downward to position a unit or a member located below the removable unit when the removable unit is attached to the body. The upstream projection projects more downward than the positioning projection at an upstream end of the removable unit in an attachment direction of the removable unit to the apparatus. A lower end of the positioning projection is located higher than a line connecting a lower end of the upstream projection and a lower portion of a downstream end of the removable unit in the attachment direction when viewed in a direction orthogonal to both an up and down direction and the attachment direction.

摘要： A heating device includes a first rotator, a second rotator, a heater, and a first, second and third temperature sensors. The second rotator contacts an outer circumferential surface of the first rotator to form a nip through which a recording medium passes. The heater heats the first rotator. The first temperature sensor is disposed outside a space extending from a first region through which a minimum recording medium passes and detects the temperature of the first rotator. The second temperature sensor is disposed outside the space extending from the first region and detects the temperature of the heater. The third temperature sensor is disposed outside the space extending from the first region and detects the temperature of the second rotator. At least one of the second temperature sensor or the third temperature sensor is disposed outside a space extending from a second region through which a maximum sheet passes.
