Abstract: A hydrophilic member is coated on the recording drum of an image recording apparatus which uses photosensitive microcapsule toner. The photosensitive microcapsule toner particles each have a hydrophilic wall and hydrophobic contents. When an image is developed with pressure, the wall remains on the recording drum since moisture in the air is absorbed in the hydrophilic member. The contents do not adhere to the recording drum because of its hydrophobic feature. Therefore, a clear image can always be obtained without transferring unnecessary materials onto an image receiving paper.
