Summary:To provide a technique allowing stable positioning of a cartridge with respect to side plates of a tray unit.SOLUTION: In an image forming apparatus, a cartridge PPK is removably mounted, and a tray unit configured to be movable between an internal position located inside an apparatus main body 100A and an external position located outside the apparatus main body has first and second side plates that support the cartridge, the first and second side plates each formed of metal and including a support part and an outside part, wherein the support part includes a positioning part and the positioning part is configured to contact the cartridge so that the cartridge is located at an image forming position. The apparatus main body includes first and second pressing members that are each movable between a pressing position for pressing the cartridge and a separation position separated from the cartridge. The first and second pressing members are each arranged to intersect with a virtual plane orthogonal to a longitudinal direction and intersecting with the positioning part.SELECTED DRAWING: Figure 14 【課題】トレイユニットの側板に対してカートリッジを安定して位置決めすることができる技術を提供する。【解決手段】画像形成装置において、カートリッジPPKが取り外し可能に装着され、装置本体100Aの内部に位置する内部位置と外部に位置する外部位置との間を移動可能に構成されたトレイユニットが、カートリッジを支持する第1、第2の側板であって、夫々、金属によって形成され、支持部と外側部とを含み、支持部が位置決め部を含み、画像形成位置にカートリッジが位置決めされるように、位置決め部がカートリッジと当接するように構成される第1、第2の側板を有し、装置本体が、夫々、カートリッジを押圧する押圧位置と、カートリッジから離間する離間位置と、の間を移動可能な第1、第2の押圧部材を備え、第1、第2の押圧部材が、夫々、長手方向に直交して位置決め部と交わる仮想平面と交わるように配置される。【選択図】図14
