An apparatus which forms an electrostatic latent image by exposing a charged photosensitive member with light. The apparatus identifies a pixel which has density value less than a threshold value and is sandwiched in a predetermined direction between two pixels having density values greater than or equal to the threshold value in image data, generates screen image data by screen processing on the image data, and outputs, for each of one pixel of the two pixels sandwiching the identified pixel and a pixel adjacent to the one pixel in the predetermined direction, an adjusted density value the screen image data.

A light emitting device includes a light-guide member that extends in one direction, a light emitting element that radiates light onto an end surface of the light-guide member, a reflective member that extends in the one direction and reflects, while holding the light-guide member, light that is emitted from a surface of the light-guide member, and a housing that accommodates the reflective member and includes a holding unit, the holding unit being configured to hold the reflective member at an accommodating position of the reflective member and configured to allow the reflective member to be released from a state of being held when the reflective member is bent in a crossing direction that crosses the one direction.

An example method of determining dot gain in a liquid electrophotographic printer is described. The method involves effecting a print operation based on a predetermined digital dot area and measuring an operating current of a binary ink development unit during the print operation. A dot gain between the digital dot area and a physical dot area of a developed image is determined based on a function of the measured operating current.
