Summary:To provide a detachable unit that can prevent damage to a positioning projection part, and an image forming apparatus.SOLUTION: A fixing device 32 as a detachable unit configured to be detachably attached to an apparatus body has a positioning projection part 133 that projects downward and performs positioning with respect to a unit or a member located below the fixing device in a state where it is attached to the apparatus body. The fixing device 32 has a first projection part 141 as an upstream-side projection part that projects further downward than the positioning projection part 133 on the upstream side in an attachment direction to the apparatus body. When seen from a direction orthogonal to both the vertical direction and the attachment direction, a top part of the positioning projection part 133 is located above a line H connecting a top part of the first projection part 141 and a lower end of a downstream-side end in the attachment direction.SELECTED DRAWING: Figure 11 【課題】位置決め突出部の破損を抑制することができる着脱ユニット及び画像形成装置を提供する。【解決手段】装置本体に対して着脱可能に構成された着脱ユニットたる定着装置３２には、下方に突出し、装置本体に装着された状態で定着装置の下方に位置するユニットまたは部材との間で位置決めを行う位置決め突出部１３３を有している。また、定着装置３２は、装置本体への装着方向の上流側に位置決め突出部１３３よりも下方に突出した上流側突出部たる第一突出部１４１を有している。そして、上下方向および装着方向いずれにも直交する方向から見たとき、第一突出部１４１の頂部と、装着方向の下流側端部の下端とを結んだ線Ｈよりも、位置決め突出部１３３の頂部が、上方に位置している。【選択図】図１１
