To obtain a squeezing roller device in which not only an upper squeezing roller but also a lower squeezing roller is easily detached and is cleaned outside.

In a wet type developing device by which surplus developer stuck to a recording sheet X is removed by a pair of squeezing rollers 25 and 27 arranged on the side of an exit after an electrostatic latent image on the surface of the recording sheet X is developed with developer, a pair of supporting brackets 31 and 32 on which a mounting groove 34 to support the bearings 29 and 30 of the lower squeezing roller 25 is formed is fixed at the insides of the frame side walls 21 and 22 of a developing device and supporting grooves 51 and 52 to support the bearings 48 and 49 of the upper squeezing roller 27 are formed on the frame side walls 21 and 22 near the supporting brackets 31 and 32.
