Image-forming device with holding unit having multiple positions

An image-forming device, comprising:

• a main body;
• at least one photosensitive member on the surface of which electrostatic latent images are formed, the photosensitive member having a support shaft;
• a plurality of developing units, each developing unit having a developer-accommodating section that accommodates developer, the developer-accommodating section having an opening in a top side thereof, each developing unit further having a developer-carrying member that is disposed near the opening of the developer-accommodating section and that develops a corresponding electrostatic latent image formed on the photosensitive member into a visible image by supplying developer from the developer-accommodating section to the photosensitive member;
• a transferring unit that transfers the visible images formed on the photosensitive member to a recording medium;
• a first holding unit that holds the plurality of developing units that are arranged in a row along a first removal direction, the first removal direction being orthogonal to the support shaft of the photosensitive member, the first holding unit being accommodated at a first accommodating position in the main body;
• and
• a guiding unit that enables the first holding unit to move between the first accommodating position and a first removal position that is separate from the first accommodating position in the first removal direction.
