Abstract
A recording unit having an electrostatic latent image carrying member and a developing member, and an image recording apparatus which assembles therein the recording unit. The carrying member is supported on a first casing and the developing member is supported on a second casing pivotally connected to the first casing. The second casing has a developing position in which an opening portion for an image transfer is provided and a blockage position which closes the opening portion. A displacement member is provided between the first and the second casings for normally providing the blockage position. The image recording apparatus includes a drive member engageable with the second casing. The drive member urges the second casing toward the developing position against a biasing force of the displacement members when the recording unit is assembled into the image recording apparatus.
